<human>: Give me the gist of the text in a nutshell

Hi Reddit, I am in a tough situation.

I will have been dating my current girlfriend for two years coming up in June. She is my first girlfriend, and also the woman I lost my virginity to. 

After the first year or so, had feelings that we were incompatible and asked to take time apart from each other. We went on a break for a few days and I decided it was best to end the relationship.

for about a month I felt terrible with my choice, but suspected it would get better. After another 2 months, I still felt just as empty inside and figured it was a sign that I ended the relationship too early. We got back together, and have been together until now.

We once again are on a break initiated by myself. For the few weeks leading up to the present, I felt very individualistic and wasn't interested in holding hands, cuddling, or any contact with her really. 

This dis-interest I believe has been caused by myself constantly thinking about how I really care for her, but I just cannot see myself spending the rest of my life with her. 

Am I wasting her time by waiting for things to change? Should I not be feeling in love by this point in the relationship? We seldom fight or argue, but we just don't have a whole lot in common. 

I would love to hear what you all have to say. I just don't know what to do and my heart is constantly feeling heavy.
<bot>: I'm on a second break with my first girlfriend of 2 years. I still feel she's not the perfect one, but we get along well and I care for her a lot. What should I do?
