In the long run it is your decision on what to do. My husband cheated for the first time after three years but we had three kids and so many years vested i thought i would give him a chance then recently i found out that he cheated on me a total of three times and he almost left for the third. The person that i am I took him back because i love him so much. The only thing that i can not get past is that i do not trust him and every day i cry because i hurt so much. We have been married for almost 8 years now and have been together since 1995. I dont want to throw it away. I am trying to make it work but it does not help that we fight a lot and i am constantly only thinking of him with someone else and cry every day. I personally dont know what to do myself sometimes. Your decision only depends on how strong can you be and can you pull through this. Ask yourself that.
