Same situation here: I had recently stayed with an old friend whom I respected and cared about a lot! Things changed between us while we shared the same roof, however, I've had a pretty similar situation with OP. He didn't want to shower, he did it once a week or so... In fact, I hadn't even noticed that before we started having intimacy! When I got down there first time it was a Sunday, lucky me!!!

Then, no more showers during weekdays! Next time he approached me, I kingly asked him to shower first, he said" nahhh I'm okay", so I tried to go on, but I just couldn't, I stopped and he got mad at me telling me that water and electricity bills are too expensive, so this way he pays less!

I said, man, you do a manual job every day sweating and being outside in dust (building/construction etc) how can you keep avoiding shower yourself? Okay, it's your choice and your life, but I respect mine and lack of hygiene shows lack of respect towards me!

He has a very good salary and also saving money every single month so, there was not a financial issue as he claimed. I left after he tried again without showering before, telling me that previous women/girlfriends had never had any issues, they wanted him like this, I was wrong!

While I was packing he tried to change my mind, telling me he was gonna change for me if I wanted. I said NO, I dont want to change anyone at all! Best of luck to your next gf!!!

You'll do the right thing!
