Hey v
Do you have an active social life of your own? If not, it might benefit you greatly to spend some time with other people, just being yourself instead of worrying about your boyfriend....there's no reason to ignore his calls or texts when you're out, if you're bright and breezy and having a good time but still being nice to him, he will not only see that you can have fun without him and are a fun, sociable person that others want to spend time with, but perhaps he will recognise that you are both enititled to a life of your own.
There's so much to say but I don't have the brain power this morning to write it! Basically I think you should try to concentrate on yourself and what you want out of life, get out and have fun and you will appreciate yourself more. Then whatever happens, or whatever decision you make, you will feel confident about it.
Best of luck
