I just need some advice really.
I have been in a relationship with my DP for 2 years and got engaged just before Christmas. We have a great relationship, we work so well together, our children are getting on great and things are really looking up. I cannot wait to be his wife and to carry on our lives together.
But there's this one issue that happens every 6 months or so. When my DP has a few too many drinks or a bit of a bad day he will bring up my past. He will make me feel small for how many sexual partners I've had and often asks very personal questions and can be quite nasty about it.
I've told him it needs to stop and that my past is behind me and I'm not that person anymore. However it doesn't seem to make any difference. We will talk. He will say it's difficult to leave it in the past, I will get upset, he then feels bad and all will be forgotten the following day until the next time he brings it up.
After a not so great weekend with him I've told him today that it is his problem not mine and he needs to either get over it or leave- he didn't reply. I feel like I've been so hasty, I don't want him to leave because 99% of the time things are great but I can't take anymore of this 
I'm dreading him not coming home but I really feel I don't deserve this either. I don't know what to do.
