Get rid of him, once a cheat always a cheat. Don't wait until he gives you a STD.
You don't MUST do everything. If you have a kind heart and you really care about him, forgive him. ONCE. A mistake you can forgive. If he does it again, back he goes to the used boyfriend store.
Other people asked questions on various topics, and are still waiting for answer. Would be great if you can take a sec and answer them
