How do you gain your boyfriend's trust back after getting high with your ex and trying to keep it from your boyfriend?
is he more hurt that you got high with your ex or that you where with him either way getting high is your first problem i dont know what drugs you use but you cant make good decisions while high even though they may seem great at the time and you wonder why nobody ever thought of that before.. when you sober up youll see they where not good ideas.i know.
stay close to the girl as well as the guy. but hopefully only as friends ;) Depends... if you trust your boyfriend, nothing - jealousy will only cause problems. If you have no legitimate reason to be jealous, then dont be. Trust your boyfriends judgement, and get to know her too... if he sees good qualities in her, perhaps you will too.
Would you trust you boyfriends brother if he said he was cheating on you and your boyfriend said he didn't?
This could be a question of motive - did he tell you this because it is true, did he tell you this because he wants you for himself, did he tell you this because he is angry or jealous of his brother, or maybe he told you this because he is just looking out for you. And it is hard to say not knowing what your relationship is with the brother in the first place…
If you are asking about topics to talk about with your boyfriend/girlfriend, then my answer is this. My boyfriend and I were friends before we started dating. try to see if you can think of topics you would talk about with friends. if you cant trust your boyfriend/girlfriend with certain topics or its very awkward, then you have a problem... hope that helps
