Need advice

Rowan • Hey everyone, my name is Rowan I am 26 years young and my husband and I have two beautiful girls and handsome son.
Okay so my husband and I went down to his parents house for thanksgiving this year. Well last night he had a lot of family come over. We were all drinking, but he had went to sleep a little later. After he went to sleep I decided to stay out with some of his family and continue to drink (I know, stupid). Well I was getting a little to friendly with some of the guys, to me I was just having fun but apparently to everyone that was there I was being a slut. I told him what happened this morning and we got over it and made up but then his family came up to him and was telling him how horrible I was acting and so on. He is now wanting me to leave and he says he feels like even though I didn't cheat on him it feels that way. I feel so embarrassed and ashamed of myself I just don't know what to do to make it better. I have decided though that I might have a problem with alcohol so I have decided not to drink anymore. How should I handle this?
