<human>: So my ex (22, F) broke up with me after she got back from a trip to Israel. On the trip she was with another guy. I've been slowly getting over it, but can't seem to make myself be interested or attracted to other girls. 

Since the break-up I've had several chances to be with other girls. I  tried to hook up with one, but the whole time I kept thinking about my ex and ended up stopping after roughly five minutes. I can't even watch porn without thinking about her with someone else. 

I realize she's gone, I realize the relationship is over but I can't seem to get myself back to being interested and excited about being with other people. How long does this go on, and what steps can I take to make this process go by faster?

Can you give me a shortened version of the text?
<bot>: Since my ex broke up with me I've lost interest in other girls. Tried to hook up with someone else, but cut it short and have had no desire to try since. How do I move on?
