Search Results: leaving after sex

I've seen many women on this website who have complained of guys leaving them after they had sex with them on the first date, and i don't even understand why they do such stupid things and come complaining about them here, i mean how can sex from the first date be any good for a relationship? It's basically a one night stand but with people getting hurt, and if the guy doesn't leave them after that then the relationship will be built on sheer physical attraction and zero to no emotional connection whatsoever which will make the relationship one hell of an emotional rollercoaster for the more sensitive partner and a headache for the other, don't people see the negative sides? The only positive side is the pleasure of sex which is as minimal as any casual senseless hookup
I mean instead of that bullshit, go find someone just for hookup and nothing else, where's the love in case of sex of a first date? There's nothing but lust, and if lust comes first then love is pretty much dead because people are just ignoring the fact that loves come first, not lust

I've been married almost 6yrs now but don't love my wife like I used to. We have 2 young children and at the moment that's why I'm hanging around. I tried to break things off a year ago but my wife had a massive breakdown!
Before we got married we had a few theeesomes with girls and kept having them after we got married. At our grocery store there was a girl who was a 10/10 I told my wife all the time she was my hall pass whenever she asked (wife's was Michael Buble) We moved areas and I added the girl from the store on FB and we started chatting, initially hoping for a threesome with her, however she wasn't into them. We kept chatting anyways which turned into everyday for a few months. She had a boyfriend so I pushed anything about hooking up. One day when my wife was away working I suggested she drive the 2hrs and hang out, half jokingly however she ended up coming over. The first time seeing each other for ages. We had a few drinks then ended up having sex all night then the next morning as well. We met up a few weeks later when I was in town again and had sex again. We both ended up telling each other that we both had feelings for each other but I couldn't give her what she needed right now (relationship) as I was still married. We still kept chatting most days until it turned into once or twice a week. We started again everyday for about 2 weeks now it has suddenly stopped. She is all I think about but we aren't talking. I've decided I am leaving my wife however that's a process! Also I didn't want supermarket girl to think I was just leaving my wife for her!
What should I do?
1. keep persuing supermarket girl even though she's ignoring all of my messages
2. Leave my wife (long process)
3. Stay with the wife
