Hi Seddit. This is my first post - please be gentle!

So, I have two problems. Context - a girl (lets call her Susan) 2-3 months ago broke up with me (somewhere between her calling things off and it being mutual). Problem is, I am 21 and we went out for a 1 1/2 years - and I really loved her. She broke my heart. Towards the end of the relationship, I was the one doing the bulk of phone calls / texts / arranging fun shit / keeping in touch, she didn't really give a shit and was dismissive.

This has led to two problems. Firstly, she has started calling me again. The last few times, I have been too busy to answer / missed the call (from work or working out or whatever). I'm not sure if to pick up and chat to her though - I need to get her out of my mind and I know she won't want what I want. That said, she /was/ a good friend and we did the whole "lets be friends" spiel when we broke up.

The second problem is a bit worse. I picked up a fairly attractive girl (call her Claire) last weekend (2nd date, go back to my place, hugs, sex and breakfast deal) - but the problem was when we were about to do the dirty, I was thinking of Susan and had difficulty getting it up. Claire was the first girl I've had sex with since. This is pretty rare for me =/ Eventually I did - and then did my duty - but then the sex (despite not jacking off for a week - record!) left me feeling unsatisfied and hollow.

Anyone got any good advice for me? In a tough spot on both accounts at the mo' :(

Thanks Seddit :)
