New boyrfriend seems too interested in other girls
	
	
		With my ex boyfriend I was extremely over-possessive, and we would have a huge argument every time I thought he was looking at other girls, even in movies etc. because it made me feel inadequate. It was this which lead to our break-up almost a year ago and I now realise that I was just being immature and irrational. Now I have a new boyfriend and after my previous relationship I promised myself to take a different attitude to "other girls", for example I know he watches porn and always says "that girl's really hot" but I try not to let it bother me because I know he finds me attractive too.
However, I found out that he has been talking to several attractive girls on a social networking site and it's really bothering me. It's not as though he just finds them attractive, he's actually talking to them and it makes me feel like I'm not good enough for him. He's constantly talking to girls on IM and it's really making me wonder if I can trust him. After my previous possessiveness I've really tried to be cool about it but it's hard. Is there any way I can talk to him without sounding needy? Do I have anything to worry about.
Thanks.
