It's definitely not easy to leave but it's 100x times fulfilling than staying in a dead relationship. I never regretted leaving. I hope you'll find strength

Girl, you know this is not normal. He's doing it on purpose and this example proves it unfortunately. He feels secure and like you're never going to take any action against his behaviour. He will not change... I know it's not what you want to hear, but it would be best if you did not waste your life on this man

That's the main problem because he only cares about stuff that affects him. I mean you can try and make him realise he's at fault, but it seems like he's entirely unresponsive and does not want to work on the relationship. The longer you stay, the more time you waste.

I was in a similar relationship and I left. I felt alone and lonely all the time while in the relationship. I'm single over a year now and I don't have these feelings any more.

That's perfect then. He believes you won't leave. Prove him wrong so he wakes up and realises he needs you.
