seek professional help..
if you r bitter and he did you wrong once, hell keep doing it you cannot trust him so leave him and its okay to gripe a lot everybody does that
its okay to be emotional in fact sometimes that's your gut instinct telling you to protect yourself and peoples' general nature does not change on a dime he will like he was before again. if you are having trouble at work be assertive if you are not doing anything wrong
Sounds like you need a confessional. Not Q&A. You already see the issue.
