<human>: Condense the text into a few key points

We had some ups and downs but they were things that I thought we could get over. A little background...he considers me (and everyone else he knows) to be further along in life than him, he still lives at home but is trying to move out soon, and he hadn't much dating experience or sexual experience when he got with me. 

He says he would rather break it off and explore so that he has no regrets later in life. He doesn't know if he ever wants to get married (although its all he ever talked about!) but if he ever did it would be to me. (im too upset to believe that right now)

For men, is it really necessary to explore everything in life before settling down even if it means giving up what u have? I've gone through similar thoughts before but I was not in a relationship. Had I been in a relationship with someone I loved, those doubts would have been there but not enough for me to just let go of the person I love.

Does it mean he just doesn't love me in that way at all in the first place? Or can this really be a legit maturing process for him? I won't fight for him or beg or anything but its just all so confusing. Seeing that I had the experience already and I know what its like out there, I'm not that curious anymore.

Another thing to mention...he knows I want to be married someday but nowhere near now. I always said I wouldn't even get married until I was at least 30 yrs old. He often talked about how he could see himself married to me and even named the children before I EVER mentioned that stuff. Why do men jump all in and then retreat? Why bet on the potential of what's out there rather than nurture what you have already? And do they ever "get it out of their system" and come back confident? Knowing she might be gone?
<bot>: Boyfriend dumped me so he could sexually explore and date around since he's never experienced that before. I want to know if there is any chance that men come back after this "phase".
