I'm [18/m] being told to get out of my Ex girlfriends[18/f] life.

OK. So, that title paints me into a corner, but I guess if you are reading this then context is probably what your here for.

First off, I want to point out that I’m a nice guy… not my own words.

I go out of my way to help people, I donate to charities when I can (Not a lot, I’m a student.) and give semi useful advice if anyone needs it.

This is a key point of the post, I gave advice it’s what I’m good at, somehow it makes people understand things but enough of my own circle jerk…

We broke up about six months ago, while at first it seemed like something we both wanted - it was really because she didn’t fancy cheating on me… well continuing to anyway.

We had an argument Because she was being petty I didn’t know she needed space and we stopped talking for a while.

To make up for it, I made her a going away present for Uni and then helped her move in to said Uni.

After this the guy, she was cheating on became her new BF but being a bit of a douche, constantly annoyed the fuck out of her. So, she asked for advice from me… at night… drunkenly…a lot.

Me giving her advice continued over the months, and during some of the time I was enjoying her being happy… genuinely this was one of my best friends and after the year she helped me through seeing her happy was nice… stung a bit but still nice. I even gave advice to her BF… Christ that was a weird day.

So, this February rolls around and it’s like none of this EVER FUCKING HAPPENED.

She refuses to talk to me at all and had to hear it from her BF that she doesn’t want me in her life anymore. This would be weird if this was out of the blue… but it’s after not wanting to give advice about the BF any more. Remember when I said it stung: it bloody burnt.

So what I’m asking is what do I do? No real idea here. Anything will help.

TL;DR Ex doesn’t want anything to do with me anymore because I refuse to help with her BF issues. What should I do?
