<human>: Can you condense the text into three sentences or less?

About 2 years ago, my ex and I broke up because we were arguing a lot and just weren't seeing eye to eye anymore. However, for the year following we continued to meet up and have sex when we were drunk.

Now, here I am, 2 years later and I still can't stop thinking about her. Any mention of her name and I can't get her out of my head for days. I've found it pretty impossible to get close to anyone since then - I've had quite a lot of one night stands since then and have been casually dating other girls... but every time things begin to get serious, I just can't stop thinking about her and I end up just ruining things. It's not even like she was a particularly good girlfriend, she wasn't my first love and I'm pretty sure she was sleeping with other people. I've even deleted her off facebook and unfollowed her on twitter - we haven't spoke in months except from once on the bus.

 No matter what I do, I just can't stop thinking about her. I'm getting pretty desperate her, reddit, I just need some solid advice.
