Search Results: afraid to make commitments

I met this guy online. I've been seeing him for 2.5 months now and I think things are good... his past and general outlook on life suggests he's not afraid of commitment, and right now he does all kinds of things that suggest he views us as more of a relationship than just 'dating.' But we haven't really talked about it. I'm not a fan of The Talk because it makes people so uncomfortable sometimes, and girls have a habit of bringing it up too soon, so I thought I'd wait for him to come to me on his own terms. Anyway, as much as things are implied, he still goes on the website we met on. I get emails in my normal inbox saying I have mail there, and I like to read them just for fun. I literally log on, read them, laugh (some of them are kinda funny) then log off. But sometimes if I look at his profile it'll say he's online, and he'll be online for much longer. I admit, sometimes I log on with my friend's profile and wait to see if he logs off, and he won't for quite a while. It implies he's doing searches and messaging other girls.

I'm not really sure what to do here. Like I said, I hate the whole idea of The Talk. I don't wanna come across as needy or whatever, but I want to know if he's going to get exclusive with me ever or if I should look for someone else who will. Guys - do you still see other girls for a while before you commit? If so, how long does it usually take you to decide? Should I be worried here or is it just a case of hanging around for another couple weeks? I just don't wanna end up hanging around for like 2-3 more months or something.
