In fact, I see only 2 scenarios here. If it is possible to fix the relationship in principle, then you need to understand the reason why what is happening in this relationship is happening. What led to this?

And here it is very important not to confuse cause with effect. If this problem is really important to you and you want to solve it, then try to sit down and talk to a man about it. Many people don't even try to do it.

Tell him what is bothering you and suggest ways to solve it. If in this way it did not work out to correct the situation, then you need to be able to end a relationship with a person who does not suit you. And to perceive it as an experience already for a new relationship.
