<human>: I'm a first time poster so take it easy on me.. lol So I broke up with my GF of 5 years about 3 weeks ago on good terms. Long story short we had just started to fall out of love I think and both had different ideas of where we wanted to be as a couple.

I went out for a night drinking with some friends last weekend and had met a girl.. we exchanged numbers etc. So this week I invited her round to my place and we had sex. It was very low key and we have both been secretive about it as I wouldn't want anybody finding out, just for the fact of it not been long since breaking up with ex. And I'm not one for bragging and boasting... 

I felt good afterwards and I feel normal about it but I can't help but think.. should I feel bad about it as it's only been three weeks? Is there an 'acceptable' time frame to do this in? I've tried to do the respectful thing and keep it low key but I know I would feel pretty bad about it if my Ex found out and I would feel bad if the shoe was on the other foot...

Can you summarize the given text in a few sentences?
<bot>: Broke up with Ex of 5 years, slept with someone 3 weeks after. Is there an 'acceptable' time frame to do this normally? Should I feel bad?
