Men are unpreditable!
One second they love you, the next they hate you.
You should have gotten out of the relationship when all the mess started. I know I know... trying to work it out seems like the "right" thing to do but it takes 2 to work it out, not 1!
You are not suicidal, its just a cry for help. Your lost and feel like crap. Your boobs hurt and your tired all the time. Your pregnant again and you know how that goes.
Only thing I can say is just stay strong for your children. Try not to stress yourself out so much its NOT THE BABIES FAULT!! That child did not ASK you bring them into this world!! If you commit suicide, not only are you killing an innocent child I would love to have (I cant have children) but you will be leaving your other child without parents!
You know damn well your husband isn't going to take care of a small child while he is trying to get his kicks!
Move out, and move on. You have a baby coming, this should be the most joyful moment, not worrying what he is doing.
You and your hormones dont mix well either. Of course your going to think all the worse.. you think that everyone is against you and no one wants to help you and your husband thinks your crap. ok.. leave him!
When he can't find anyone else to mess with he will come crawling back like a dog with no tail and then it will be in your power to shut him down like he did to you!
