Context: Have been entertaining 2 different one-sided LTRs for the past 3 years with various FWBs + plates that come and go. Have told both I never plan to legally marry. They accept this on the surface but considering one is 27 and the other is 34(and they’re women), they likely delude themselves

Some poor past choices led me to have to rebuild my life from the ground up. I’d like to think we’ve all been there at one point or another. During this time, 2 plates behaved well enough to earn FWB, and then trial-LTR status. Bitch Management style works wonders if done correctly. While one of these has been smooth sailing, the other I chose to cohabitate with (Big Mistake 1) out of convenience, our places rent being paid by her (Big Mistake #2). Even though the investment I have in the first girl is stronger, and her RMV/genuine desire in me is higher, and the 2nd girl demonstrating she’s not really LTR material several times, it’s the 2nd girl I find myself slipping into oneitis for and resenting for not being like the 1st. I know I’m better than her, I still game/see other girls, and I know my SMV is on the rise while hers plateaued and is on the decline. So why does the latter relationship spark more desire/attraction in me than other girls I am seeing? Why have I begun to let it weaken my frame?

Attempt to answer own question: The 2nd LTR sparks resentment for a few reasons. First is the 2 mistakes mentioned above. We all know why cohabitation is mostly a bad idea, and her paying the rent gives her soft power over me. Even though she’s made no direct/indirect mention of it so far, its presence is felt. Attraction was high during the first couple years of non-exclusive dating but gradually faded, as it does with cohabitation. There were a few examples of her being more attracted to other people/doing things she hasn’t done with me during this stage too, which I accepted and made a mental note of but forgot about as time went on. Last is her crossing several soft boundaries, which she immediately apologized/made amends for but the instances mostly followed the same pattern and left a bitter taste in my mouth. She still adds value to my life, but has proven this girl is nothing to be taken seriously. It’s this part that’s proved challenging and is what I’d like more perspective on. The situation is, at the end of the day, my fault and responsibility. I should probably continue to rebuild my life, and doing my best to detach from her, move out when the lease is up in a few months, and see other women.
