Should I give my husband another chance?

me and my husband are married for almost 8 years, and in that time, he has been insensitive, inconsiderate, conceited, unappreciative in all that I do for him, but the thing is he's my first love, before, i used to let myself be a doormat for him and he obviously knows that i really do love him very much that he took advantage of it, but now, I'm trying to be strong and control my feelings for him, he tried to accuse me of having an affair with someone else but it turns out that he's the one who's doing it, and it kinda hurt me. I used to call him "daddy" but now someone else is doing that, it kinda make me feel jealous and scared that i might lose him to this other girl. So if you please help me with this problem.
