FWIW, I thought I'd throw this into the mix....
I was listening, on and off while driving, to a really interesting podcast yesterday.
It was actually about a completely different subject, but it touched on some excellent points about life in general.
Some of the points were about overcompensation.
Like how lonely people (not saying the OP is lonely, but it's relatable) many times end up driving people away by plain old trying to hard.
It made me think of a woman (I'm a woman too btw) that I met via a male friend a couple of months ago. We met over a casual lunch, and Jeebus, by the time the lunch was over it's like she had planned out the rest of our lives together. It wasn't as uncomfortable as it might have been only because my long time friend was there as a buffer. Over the next week I saw her twice more, once with that friend, another time when I had mentioned I was meeting another friend somewhere, and she more or less invited herself along, and just showed up. The 2nd time I saw her she did say she was lonely (she was new in the area), and my friend and I later talked about that alone, both of us agreeing she had to learn to take it easier, or drive others away.
She had actually invited me and the 2 other friends to dinner the next night, and followed was a flurry of texts to all of us relating to it. Then, it must have dawned on her how over exuberant she was being, suddenly texted she couldn't make it, and......silence since then.
I'm sure we all 3 realized she felt embarrassed (we didn't discuss it). I have to wonder how differently it could have gone if she had just been chill about the whole thing. She was in fact very nice.
Our OP has not been that over the top, but is heading that way if he goes ahead with the apologies, explanations, further planning and falling for this other person.
Take it easy my man. Just flow.
