So basically, I'm at university and I went to a party and there was a girl there, and she seemed quite flirty and talkative. Later on in the nightclub, I tried to kiss her and she said she had a boyfriend and showed me a picture on her phone with her boyfriend as her lockscreen and I thought nothing of it and assumed I was just misreading signals. However, I get back and see she has added me on facebook and followed me on Instagram, so I message her and get her snapchat.

For the last two weeks we have been snapchatting daily, and when I open her snapchat and don't reply she will message me something along the lines of "ignored" or "you going to reply then mate". Then last night, she agreed to go out somewhere and watch tv at mine, and we discussed funny sexual stories and what sexual things we are into.

Her and her boyfriend have been going out for a year, and without being big headed I think I'm better looking than her boyfriend. Do you think she is just being friendly, or she wants something more with me such as to have sex

I don't want a lecture on how I shouldn't do it, I know what I'm doing is terrible but I get a thrill out of having sex with girls in relationships.
