Girlfriends Step mother GRR

[Ion22]

Ok well I have been going out with my girlfriend for about 5 months now and it is going GREAT I love her so much but there is one big problem her stepmother and her brother. Now her birth mother loves me we have a great relationship I work on her car and do other things with her she is one of the sweetest ladies I know. Now I am 19 years old and my girlfriend is 18 she has one year left of high school and I will be on my 2nd year of college. We are very serious now call me crazy but the first day I met her I told her I was going to marry her there is just that feeling and I truly know I will (ps my dad did the same thing to my mother and my mothers father with my grandmother go figure) Now my whole family loves her my little cousin wants to be like her and so on. Like I said there is just one problem her stepmother and her brother. Now I understand that her brother doesn't want to see his little sister to grow up but there is a line when it gets crazy. I see myself as a stand up guy I hold doors open I open the car door for her every time I do the the "old school" things my father taught me. Now her brother is an ass he talks **** about me to her saying "when are you going to break up with this kid he's an asshole" bla bla bla. Now I have never once done anything to make myself look like an ass at all. Her stepmother makes her clean the whole house even her dads and step moms room (<--weird!) every Thursday since she was 10. Now she has a 22 year old brother and a 11 year old sister but they don't do a thing. Now to day was kind of the breaking point because she cleaned yesterday like she was told and I didn't see her (don't really care gave me time to work on the car lol) but she went out with her cousin to do what girls do and shop and she was then going to work from 4-8 I was going to pick her and her mother up and go out and see a movie now her brother calls me and says "Den my step mom is going to pick her up" "Why we where going to go out and see a movie with your mom" "she needs to be home she is not going anywhere tonight!" Now he said this with an altitude and then I said ok and hung up. My girlfriend then calls me around 7:15 and says why are you not picking me up I told her what was said with me and her brother and she then called her step mom and the whole reason is because she was out all day and did clean! Now don't ask me what is wrong with this women I mean her dad is so whipped he want do anything. Now remember it is summer time and she still has a curfew now the funny thing is I live 10 Mother ****ing house's down from her! Now I have done nothing but good to this family and It just suck that she is treated like Cinderella I mean she has done nothing wrong to any one of them. They treat her like Sh!t and she just takes it and I have to pick up the pieces! I mean this has been going on for the last 5 months and it just suck because I know she will not stick up for herself. I just don't know what to do any more!

Thanks for whoever read this long rant! God this feels good!

Ps Here is to her step mom and brother
