My girlfriend of 4 and a half years has been going through a lot of issues, predominantly family issues. Her whole family tries to use her. A quick run down of what she's been through. She was raped by a man who was a "friend" of her mothers, her dad was a pedaphile, her mom was on drugs, she had her first child at 19 which was a special needs child who lived to be 7 years old until she died in 2010. My girlfriend has also lost a few family members, that's just a quick run down. What I need advice on is should I stick by her she goes through fazes every month or so where she doesn't want me, then after a few days she's in love with me, we had and to get married this August (2014) idk if that should happen, I love her a lot, we have a son together he'll be 4 in July. Her and I have also been through a whole lot but somehow stick together; however, it's to the point that I'm not happy at all, don't want to waste anymore time I'm not getting any younger her and I are both 29. She claims she's going through "a midlife crisis" and she's scared of getting old and she says she's never been with "anyone this long before" I need advice. Thank you.
