<human>: Can you provide a brief overview of the text?

Hi everyone,

New here, but have been lurking for some time. 

So my girlfriend and I of 2.5 years, who I lived with for ~2 years, broke up recently. We both were abroad 4 months ago, so we did a long distance (open) relationship for the 6 months prior. Unfortunately, two of the last nights a good friend of mine I made there and I hooked up, and that really affected my perspective on my home relationship.

While my friend and I both agreed to be friends, I still had some residual feelings for her (which it seems she reciprocated). Nonetheless, it caused me to be disinterested in my once happy, great relationship at home. While I was attracted to and cared for my ex, I simply lost interest in a big way.

We tried to work it out, and spent a month with required nights out and check-ins. Despite that, at the end of it all, I still felt absent, and broke up with her to stop the pain on her end.

Anyway, I met up with her a few days ago, and for the first time in a while, felt finally attracted/interested in my ex in the way that I missed. After that I really regretted breaking up with her, because part of me thinks we could have worked. The other girl doesn't even stack up to her at all.

I'll be in the general area of my ex this summer, but then I will go on a several week road trip with friends (including the girl I hooked up with). Regardless, with this moment of clarity, part of me wants to give it some time, and then get back together with my ex.

Basically, does it sound crazy for me to want to get back together with my ex? If not, is it advisable? General recommendations?

Thanks!
