Okay, so I have this dilema.. Need you to listen and give me your honest .. Open minded opinion :

So, I started dating this " great " guy about 5 months ago and at first of course everything was peachy and rosie as usual... about a month in a half into our relationship I got up enough courage to tell him that I really cared about him and that I was falling in love with him. I also told him that I wasn't telling him this cause I wanted him to say it back to me and that I hope this doesn't push him or scare him away. He told me no absolutely not and things still where great between us after that so I thought nothing of it. Then we are driving in a car a week later and I kind of suggest to him why we are not friends on face book and he says he likes to keep it that way cause he doesn't want me to read into things that might not be true and he doesn't want to read into things on my page that may not be what it truly is, so I left it at that and a few weeks later requested him anyways .. Well, he never excepted my request nor did he even mention that I requested him. He didn't say anything and I didn't bring it up either. By then I can see a little bit of tention between us. Well a few weeks after that we got into a little argument and he didn't call me all day which is unusual cause we speak more than 5 times a day... ( by the way he was the first one to introduce me and tell everyone that I was his GIRLFRIEND not me ) that same exact day his friend that he introduced me too was also going through something crazy with her boyfriend but the difference with her is that she was a little physcho and she said she was going to kill herself so I being the good friend or whatever went over to her house even though I knew that if he found out he was going to flip out on me ( which I completely understand , cause I wouldn't want anyone to do that either ) I was trying to make sure this girl wasn't gonna do anything to herself... So anyways that night she gives me her password to face book to go onto his page and see it if I ever need to .. She swore to me that she would never ever say anything to him about that I went over there to help her. That night he wound up calling me anyways and I didn't answer and he said that he was upset and he didn't call me that day cause of that. I didn't answer him till the morning... Well anyways we had a long convo over dinner a week later and and he said things like oh' you have to let me chase you and that we were moving to fast and stuff and he just wanted to slow things down and whatever I understood and we decided to take things slow but nothing changed I was still his girlfriend and he was still my man.. Then all of a sudden his daughters mother decides to take him to court for full custody and and I'm over here trying to help him out and be there for him and be a supportive girlfriend and he in many ways pushing me away and in many ways still wanting me there .. You know what I mean? So, I'm still checking his face book page throughout all of this and it comes to my attention that he is talking to this one girl heavy and that they hung out like on a Tuesday night and that they talk on the phone for 2 hours at a time, they have these long meaningful convo's and she's telling him " I love u boo " and that last night I knew it that I really loved you all these things.. So I confront him and and he wants to know who told me .. So obviously I'm not gonna go back on my word and I do not rat out the girl that gave me the info so I made up some story... everything was fine after that for about a week or two and everyone is like look pull away a little so he can come closer to you , so I do that and that Friday I called him in the morning on my way to work just to speak to him and he's sounded really distant and upset ... he's asking me what I did last night and I told him I went for a few drinks with one of my friends and it seems as though he got ticked off and he abruptly was like " I'm gonna let you go yo " and I couldn't here him cause of the background noise so I said to him " what did you say hun " and he yelled at me.. I told him NOT TO SPEAK TO ME LIKE THAT and he was like in a softer voice " I will speak to you later " and he never called me after that.. All weekend he didn't call nothing.. That Wed I knew he was having his first court date re: his daughter and I asked a couple of my friends what I should do that it was fucked up if I didn't call .. So I called being the bigger person... I let the phone ring once it rang twice and then he pushed ignore cause it sent me right into voicemail... I left him a message and said " I didn't want the day to go by with him thinking that I didn't care about him and his daughter cause I did and that I was concerned , but that I didn't appreciate him speaking to me like that... and I told him that I was there for him and I really wanted him to give me a call and let me know if he was okay " and I have not heard from him at all....... I love this guy but honestly I need an opinion of what to do cause I have no clue what happened and its killing me to think and know that he is out of my life just like that... oh and by the way... all of a sudden after he stopped talking to me the girl that gave me her password info all of a sudden changed her information completely and now I can't go on his page anymore... WHAT SHOULD I DO ???? HELP PLEASE !!!!
