<human>: I've been seeing Oliver for about 5 months now. He's an absolute perfect gentleman in all aspects. He listens to my ideas about anything and everything, and in regards to our relationship right now, we are very open with our thoughts and feelings, even the negative ones. 

Things have been going really great. He is a kind and virtuous individual and I like him so much. However, he wants to be friends with his ex. We have discussed it and he says honestly he doesn't want to be with her physically, but he still wants her in his life as a friend. 

I am uncomfortable with this. 

Am I wrong for feeling this way? Does this make me seem crazy and controlling so early on in a relationship? I really do not want to make him choose, but I feel like even just having this uncomfortable feeling and discussing it is making that implication. I feel really bad about this. Does anybody have any advice?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Uncomfortable about my current BF being friends with his ex. Do I just suck, or is okay for me to feel this way?
