I am not sure why I am posting on this site… I think I just need some advice from people who have gone through the same thing…

i have never been one to put myself first and I have never wanted to hurt anyone’s feelings… I have for the past 2 months really been thinking about me future and what I want… I have been with my fiancé for 6 years and I am not sure if I should marry him… I do love him but I feel like if I choose to marry him I will be sacrificing myself and will end up hurt in the future. I have been in denial for some time now… as an outsider please advice… my fiancé has a son and has cheated on me with his child’s mother about three years ago… this is something that I can’t seem to forgive or forget… and because of it I do not trust him… he is pursuing a career in music and has been away for 6 months now and I have to just not think about what he is doing day to day. I have always wanted to have children and since the beginning my fiancé has changed his mind about it 100 times. I had enough called it off about 4 months ago but he convinced me that I will get my family someday… in a conversation a few weeks ago he could not give me any sort of time line on when we will get married and start a family. I have been really digging deep to see if I want him to be the father of my children… I have a really strong feeling that he does not really want to have more children and that he will prolong it until it’s too late. I really want my husband to want a family as much as I do. If I was guaranteed that breaking up with him would not hurt him I would do it in a second… and now realizing that he will never break up with me it’s all on me… I am having a hard time figuring out what to do and it really hurts that he has no idea something’s wrong…
