I think it depends on the person. Some men are nice, and some men leave you for another woman. x
If you are getting that vibe that you are a burden, it just means you are a sensitive person and that you feel like something's up?
Like the last guy I dated was seeing other women when I couldn't find full time work and actually was really attracted to them, complimenting them, while treating me really poorly, but when he was in difficulty, I was there. When I had a job, he'd badmouth me to the bosses to get me fired with those women he was cheating on me with. I was feeling like a burden, even if I wasn't, because it's not like I ever asked anything to him, and actually one of the things he had been spreading around about me was just that. But actually he was the one who was a burden. Some people use others and move on.
Some people are more out for themselves.
But I know some men, who say moved across the globe so that both they and their wives/girlfriends could start from 0. That makes you want to have that expectation, but you shouldn't. Some people do that, some people don't do that for love. Some settle for just really bad sex.
My current boss is also using me, a lot of people lie, but he didn't give me the management position he had promised me, so in the end most men are turning into that. Liars, cheaters, bores. All men are this way now. We must either stay single, or if we marry Idk how to deal with things, to be honest. If I had a daughter I wouldn't know whom she'd date. She'd probably have much more taste than I do anyway. The problem is that bad women raise bad men. The woman who bullies another woman, that's setting an example for the man.
