<human>: Give me a shortened version of the text

This is a throwaway account.

So my girlfriend broke up with me one and a half months ago. I'm still young (23) and like to socialize, but I'm still not close of being over her.

I guess I still force to take this opportunity to go out with girls since I haven't been single for 4 years. My problem is that whenever I get a girl home from the bar and we have intercourse she assumes there's something bigger than a one night stand going on. 
Is there a way of letting the opposite sex understand very easily, without making them feel bad that this is just a one night stand?

I feel like I'm doing something wrong. I've been with 4 girls after the relationship ended and each of them always thought it was going to be something bigger than just sex. I'm seriously not looking for anything now and I know it's a cliche to say "I just got out of a serious relationship and I'm not ready". I even told this to one of the girls straight away but it didn't make any difference.

I always go with the ones I know somehow already, talk to them in the clubs and things go forward from there. Then next day they are asking if we can go out for a movie or something... I'm just not OK with messing with peoples feelings like that and I hate the conversations I have to have to try to make them realize the situation. Oh and it usually ends the way that they think after some time they can try again if we remain friends and I get over my ex. Damn I feel like a douche.
<bot>: not ready for a new relationship and trying to get one-night stands but I'm doing something wrong because the girls think otherwise.
