Hi everyone. 

I recently met a great guy and we've been dating for just under a month. We get on well, have great chemistry and he seems like a decent guy. 

The only problem is, I recently learned he just broke up with his ex girlfriend 2 month ago, and they were together for 2 years before they split. And this has put a seed of doubt in my mind over whether I could just be a "rebound". I know everyone moves on at their own pace, and he does claim to be over her, but there's a part of me that is dubious. 

Also, they're still friends. Not that this kind of thing bothers me, but with the split still being quite new and all.... well you can see why I'm a little cautious. 

My question is, do you guys think it's too soon? I was badly hurt from my last relationship and spent a lot of time working on myself to get back to a good place, and the last thing I want is to invest more of my feelings and time in a guy who may just be trying to rebound from his last relationship.  
I'd like to know your guys' thoughts/advice. Thank you.
