<human>: Summarize the given text in a few sentences.

My girlfriend [22/f] and I [23/m] have been dating and seeing each other exclusively since around mid-January. We have a lot in common and we are able to hold conversation really well. Theoretically, we should work really well for each...

however, I just can't seem to feel attachment to her. She stays the weekends at my place and that is fine but by the end of the weekend I am ready for her to go home. There are moments where I love hanging out with her but then there are moments where I just want her to leave and not be bothered. I feel like if she left or we broke up that I wouldn't be bothered in the slightest. 

My problem is that this isn't the first time. I've felt this way about a lot of women that I have dated. I usually get to know them and they are great at first but then I feel like I get bored and, over time, I begin to shut them out. The feelings that I mentioned earlier about "not being bothered in the slightest", I've had these feelings before with a lot of women and I can't seem to figure out why. I'm not sure what kind of problem I have but I definitely feel that it is interfering with my dating life.
<bot>: Started dating girl, gets bored and just wants to be alone. It has happened with most relationships that I've been in.
