Trust...I know all about that, time is a great healer, and it will take a lot of time to overcome this. When you break a trust, whether or not you meant to hurt someone, you did.

If he loves you, every day you are together, just be yourself and communicate. He has to know you love him, and there isn't anything you wouldn't do for him. I don't think you have to go as far as getting a new phone or SIM...new number is good enough.

As for what AAAAA said I agree totally...never put yourself in a situation like that. From the get you should have said WTF, leave me alone, I said no, and I mean it. I would have told my B/F right then and there, "Hey, your so called friend is hitting on me, get him off my back." You had proof with the texts, so it's not like he wouldn't believe you.

All in all, let time take it's course, if you were meant for each other, everything will eventually be ok.

GL and God bless!
