<human>: Summary:

Girlfriend and I have been dating for seven months. It has been good but there is a major issue thats coming to a head.  Her step dad has become in my opinion jealous of the relationship.  She lives at home with her step dad and mom and is close to them.  

Setup:

The step dad started out nice but has became less social towards me. I felt the biggest change happened when she began talking about moving out. It has gotten to the point where he is now causing un-needed drama in the our relationship and his family by completely ignoring my girlfriend after we spend anytime together.  

Evidence:

Some of the things that he has done are: intentionally declined tickets to entertainment events and, canceled planned outings when he felt she was spending too much time with me.  When he did these and other things he would explicitly let GF know to rub it in as a punishment.  It has become a big issue and has been a drain anytime we're together.

Her:

She has reassured me of her love and that I am the best guy she has dated.  She dated some bad characters previously.  I am her first boyfriend in a few years. Word from his friends that they have "leaked" to GF say that he feels I did something wrong but, I am unaware of anything.  These "leaks" generally only occur when me and GF are hanging out via email/text.

Me:

I am starting to get tired of dealing with the drama.  I love the girl but I don't want to ruin her family relationships and honestly I don't want to deal with the fallout if she was completely alienated.

Questions:

A. Should I end it and not be the one to destroy the relationship between her and her step dad?

B. I am wondering what are the chances she is going to end up siding with him and breaking up with me? (She explained to me that before me she was unhappy now she's happy)

Could you distill the essence of the text into 1-3 sentences?
<bot>: GF & her mom are being emotionally tortured by step dad because she is dating me and I am unsure if I should continue the relationship.
