Is it normal to accuse my boyfriend over everything?

He must be behaving in some way to make you not trust him. Try to figure out what that is, and sit down calmly with him and discuss it, without any accusations.

I was in a relationship for 3 years with a man who liked to flirt. Looking back on it, I realize that he loved me, but he was just very socialble.

if you're not preoccupied then i suspect you spend a lot of time with him/thinking about him.

When you have more things to worry about hopefully you should start appreciating him more and things will turn out for the better :)

do the guy a favour and break up with him.

NO

You aren't ready for a relationship. Break up and let him find someone who's ready.

Well this won't last long.

OHMYGOD! I went through the same thing , here's your answer. Q: Would I rather be happy or constantly paranoid and unhappy? What am I losing if I break it off with him? What am I gaining? Now, What am I Really losing again? Is he really worth it? ... No really. Think about yourself for a change, and don't be afraid of change.

I agree with lc1988, if you have trust issues when you're in the same area, you will almost certainly have trust issues when you are long distance.
I have a few questions and I'm not trying to pry you can ask yourself these without posting, what made you think he was cheating in the first place? (was it an event or something that happened are you just afraid that it may happen?) Why are you accusing him of bad intentions? (did he do something or is he just being very secretive, is he doing things behind your back that you don't approve of?) Is there any way you can just go to a college close by, if you want it to work then I suggest staying near him, but of course if you can't well I'm sure you'll figure something out (long distance relationships are hard to keep going, especially with trust issues; it seems like you really want this to last and work since you're taking the step of going to a therapist)
Relationships are going to have their ups and downs, everyone goes through them; it just depends on how you deal with the issues at hand that keeps it going healthy. It may be bliss in the beginning, you're getting to know each other and haven't really established anything yet, then you get comfortable with each other and the flaws and such come out and you get to know each other better, talk to each other you may not like what he says, but if you listen you may be very surprised at what the other one says or thinks (remember people are not mind readers and if you haven't explained what is bothering you (in a civil manner not a heated argument)he may not know what is hurting you or causing you to have these trust issues.
If he says he has good intentions, he may not realize that certain things he does or how he acts is hurting you. Not sure if I helped at all, good luck and I hope everything works out.

I agree with both the comments above.... YOU may realize how much he should appreciate you; but guys are so dumb!! Odds are he's going out with the guys instead of sitting home pouting over you leaving...
I am exactly the same way as you are as far as jealousy... I was actually starting to think I wasnt normal... lol... anyways Ive been cheated on so many times I dont even have a bit of confidence left in my soul. I always had guy not treat me right and abuse my love for being naive. I caught on quick but I still havent learned. I got with the guy Im with now 2 years ago; everything was fairytale perfect until I got pregnant. Instead of this being the most joyous year of my life (new daughter) it has been a complete disaster. I always catch him in lies about porn and looking at everygirl who even looks mildly attractive and it hurts so much. He tells me he only has eyes for me and he loves me sooo much but it's been such a strain on our relationship.. and every other one Ive been in. I know; I could go on forever and I may have a lil too much to vent.. Im sry! haha!! I do hope for the best with your relationship and hopefully he wont be like every guy Ive ever met and break your heart :)

If you're going away for college in another city or whatever, things will probably get worse. Brace yourself.
