So how do I actually start...
I am a twenty one year old femal been in a relationship for six years with a guy of 26 he is my first love and I can't see my life without him .
These days are a bit difficult as I have taken a opportunity to come to the usa for a year , I am from another country and he said he will wait .we have been living together for 3 years got engaged last year but he broke the engagement as he was seeing another girl .
We have broken up about three times where I moved out , as he either was busy texting other girls , I honestly do not know if he has cheated on me , my parents do not like him . They think he minipulates me and he is not honest with me.they have mentioned it a few times that they have seen him with other girls . I honestly do not know what to do any more and how to not be scared of losing him I really love him . Now that I am in the usa and not in my country I am trying to trust him but it is difficult . He was talking of getting married when I come back how do I make our relationship work and how do I try to trust what he say?

You said you've been with him for 6 years. You're currently 21 and he's currently 26. This means that you were 15 and he was 20 when you two first started dating. That alone is a problem in itself.

The two of you lived together for 3 years, got engaged but he broke the engagement because he was seeing another girl? So, he cheated on you. Problem #2.

Your parents don't like him and have seen him with other girls. He text other girls and you don't know if he's cheated nor can you trust him. Problem #3.

The best thing you can do for yourself if let him go and move on with your life. You're 21 and have been with someone since you were 15. You think you can't live without him because you've never really "lived" any other way.

Break off this bad relationship and go enjoy your life, find yourself and stop worrying about someone that has no respect for you.

Any man who breaks off an engagement with his girlfriend of 6 years because of another random female is not worth it.

You can't force yourself to trust someone. If you don't feel it, you don't have it, and why should you? You already broke up with him once for seeing another woman, and that was after you got engaged. Wake up. Meet as many people as you can while in the US for a year. You are much too young to say something like 'I can't see my life without him,' and besides, that doesn't sound very positive. It just sounds fatalistic, like you are stuck with a womanizer because you fell for him when you were a mere 15.

You don't have to trust him, or make the relationship work, just dump his lying, cheating a$$, and find out what a real man is about. Of course you have no clue about real men, who don't cheat, lie, and chase women behind your back, because you have been stuck on loser boy all your life.

Dump loser boy, and see what life is really about. You and your parents will be very relieved and happy.
