My husband thinks i'm over reacting !!!?

My husband and i have been married for 8 years now. We have had our ups and downs for years now, in the past he has cheated at least with 2 different women and one now has a kid from him that is now 3. (something i have never done) and be with oAfter counseling and ALOT of heartache i'm trying to get past the past.We even moved 10 hours away from my family and friends to get away from the drama, when we moved we decided i would stay home ur kids since we are all alone...i have always told myself that i'm gonna try this for 1 year and then i can walk away and tell my kids i tried and know 100% that we did everything and it didn't work. things were goin good for the last 6 months when last night he didn't come home or even call and say he was going to be late...after 3 hours of waiting i was completely paniced and even called his boss and asked if he had worked late or al least knew where he was...his boss said he left before 5 and he was pretty sure he and the guy that carpool together were coming home, i was REALLY upset because we live in a big city and i honestly thought something bad had happened...at this point my son needed to be at a football game and i was trying to drive him but had to turn around because i was shaking SOOO bad, when we got home my husband was getting out of the shower (we were gone 5 minutes at the longest) and was drunk....said he had to go to the bar because he was with the guy and he was not gonna be controlled and that's why he didn't call!!! he swears he didn't do anything wrong but i am furious!!! DID I OVER REACT? as far as i'm concerned he lost his rights to go out with the boys when he screwd up or at least screwed!
