How can my boyfriend trust me?

You've already done the damage. Explain to him that you have insecurities and why you had motive to call and ask. Just be honest to him and maybe he'll respect that. Tell how much you don't want to get hurt by him and you just found out what an honest guy he really was and you'll work on your insecurities about him. NOTE: He needs to do his part too on showing you his loyalty, or else you wouldn't have thought he was cheating.

Why should he trust you when you don't trust him? It's a two-way street, my friend.

Confess to him that you know what you did was wrong and you are sorry. Tell him that you really do love him and don't want to lose him, and that you want the two of you to work together to rebuild that trust.

It can be done if you are both willing to work on it. Good luck.

Did you have very solid evidence? Did you have reasonable doubt? You must make sure you are 100% (or very near to it) that he did. I think what you should have done was talk to him first. He just might tell you the truth. If you doubt, even after talking to him, then call the girl. But talk to him first. Trust is a very fragile thing.

if you think he was messing around and you check it out to releave you consious I dont really see where the problem is. yeah he may be a little upset that you didn't trust him enough but flip it, if it was you he would check up on u wouldn't he. i wouldnt feel that bad about it. everybody does that at some point its only nature to protect ur self. he will stop being angry. unless thats a cover and hes really doing something and hes being dramatically upset to hide it.

Trust is the hardest thing to regain. The best thing that you can do is be a loyal girlfriend, but there are no guarantees. If he resents you and holds this against you you may have no choice but to end it.

u answered your own question. "...lost my boyfriend's trust..."

You should apologize to him and shut up! First you go and accuse some chick and then you go announce it here. Can you not keep anything personal between you and your BF?

Heres a new idea- If you two have issues, talk to HIM. Not some chick who looks guilty or even to us. TALK TO HIM.

i'm really sure about how you can earn his trust back but i think you are being dumb about this situation. obviously he was doing something suspicious behind your back to make you feel that way and that you aren't the wrong one he is

Sometimes once trust is broken, it can't be repaired. All you can do is to be emotionally stable, allow him his feelings, and don't force him to trust you until he's ready. If he ever is.

trust:

lost in an instant,

rebiult over years.

its going to take a while but it can hapen,

hang in there k?

wit luv nik.

i agree with inlovewow.

Apologize, don't do it again. If you can work through this, it shows signs of a good strong relationship.
