I have been living with my girlfriend for almost 6 months now, and we have been dating for over a year and a half. We are both 22. Now, I have known from the start that her mom is a little out of it, and recently it has been bothering me more and more, but I am wondering if maybe I'm just being to crazy about the whole situation. I will try to make this unbiased, but I can not stand her mom, and think she is seriously fucking nuts. Backstory on the mom: Divorced, living alone, kicked my girlfriend out of the house when she was 18 (my girlfriend has been on her own since, paying for absolutely everything herself and because of it she has to work full time to afford going to school and paying rent and food). The gf works extremely hard, going to work 3 days a week and working the other 4, and is a clean cut girl (no drugs, occasional drink). Now, the mom also adopted 2 kids, and my gf's younger sister still lives with her mom as well (she is 16). My gf's mom has never been there for her anytime she asks. When my gf had no place to stay (due to her roomate having last minute issues and deciding to give her 2 weeks to move out), her mom would not even let her stay at her house. Her mom has the personality of a 13 year old, and likes to come over to our house to "hang out" like once a week. This bothers me, because I am not ok with a full grown woman coming over and trying to hang out with her daughter and boyfriend, and I have voiced this the the gf, but she says "I should respect her mom more." Its hard for me to respect a woman who has not done a god damn thing for anyone in her family. The mom recently took her 16yr old daughter out of school for a week to visit some guy she met online 500 miles away. They were gone for an entire week, then she randomly shows up at our house, uninvited, and proceeds to stick around and ask for a beer, while she tells the whole story. She also has a tendency to drop her 2 adopted kids off at our house and dissappear to go out to eat with her friends. My gf has no problem with it (which I do not understand), but I do not want to have to babysit every week for an entire Firday afternoon. The mom will occassionally ask us to go out to eat with her, then when the bill comes there is an awkwardness because she either wants to split it or wants us to pay. I was under the impression if you ask someone to dinner, you pay. The mom is a nurse and is always saying how she is broke and how we "have so much money" because we go out once a week to eat. I'm sorry, I fucking bust my ass at work and I am still broke as shit.. I'm a college student for gods sake. Maybe if you are broke you shouldn;t have adopted 2 more kids on top of the 2 you already had. The mom has even gotten mad at me for looking away for a second while shes talking, almost like I have to give her my undying attention. It drives me fucking nuts.. I guess it's little things like this that bother me, mostly because I come from a family where if I go out with my parents, they always pay, and my mom isn't trying to be 20 again. I can not imagine marrying this girl and having her mother be there, and I am shocked my gf still talks to her mother, given she has done absolutely nothing to help her.. Am I crazy?
