if i was you, i'll definately dump him no matter how much i love him. it was really hard to maintain a relationship where there's no trust anymore. you're the only one torturing if you still with him. this guy will definately not appreciating you, cause he know you loves him more than he did. once he cried, you'll take back all your words and continue be with him no matter what he did/betrays you.
i'll nvr accept to hv such bf AT ALL.
