How do you prove your boyfriend wrong?

[Princessa28]

My boyfriend would always compare us to his older brothers relationship and compare me to his brothers girl..His brothers girl cheated on him with 5 guys while his brother was over seas.. My boyfriend constantly thinks I'm going to do that,even after I tell him I'm not that type of person. But he doesn't listen..I hate when he compares me to any girl who messes up because I feel like he doesn't know the real me.. How do I show him I'm different ? when he doesn't listen to me..

If he's like that, there isn't much you can do. Just be careful and don't give him any reason to suspect anything.
