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

I'm a divorced 35 yr old father of 4. I'm seeing a girl [43]that I care about but have no long term potential with. We've been together for 3 years on and off. I've been honest with her about my feelings. Even saying to her that I don't want her to move in with me ever and I won't promise to be there for her.  It sounds harsh, but I will always be upfront and honest about my feelings. I don't want to lead anyone on.

During the past summer I went to Mexico for a couple weeks and met up with a childhood friend who I hadn't seen in about 20 years. She was there with her family at the same time. We hit it off right away. I haven't felt like that toward anyone since I dated my ex-wife (although that was didn't turn out well). When I got back from vacation I broke up with my girlfriend and the friend and I tried long distance dating. She lives about 4 hours away by car and we found it was just too far. We're both are divorced with young kids and there isn't any way to be closer in foreseeable future. It was devastating for me to give up on that. We've stayed friends and continue to talk. 

She asked if I want to come up and see her this weekend. I've missed being with her so much that I really want to go, but part of me is afraid of the inevitable hurt that will come after leaving. I also know it will also be the end with the girl that I'm see now, since I would tell her where I was going.
<bot>: Should I go see the girl I love knowing there is no chance beyond the weekend and end the relationship I'm currently in?
