that doesn’t mean he’ll lose interest in you, but if he already had some insecurities about whether or not you are into him, this will stir up his insecurities further and he’ll keep doing and trying things to “make you like him” so he can feel secure. So, for starters, I would say that the more insecure he is about you liking him, the more of this stuff he’s going to say until he’s convinced that you really like him a lot.
especially if he feels some amount of insecurity about how much she’s into him.
So from his perspective, this is a perfect situation: He still gets to be technically single but also has your ongoing exclusive commitment, sex, and companionship. So if he starts feeling pressure from you for him to get into a relationship with him, he’s going to pull back… It’s because he doesn’t want to be in a relationship…
Or if he feels that the current dynamic is feeling too much like a “relationship” to him (whatever he defines that as), he’s going to pull back. and no amount of asking, begging, hinting, pressuring or convincing is going to change that!
What I am saying is that in the beginning phase of the relationship, it’s common for one or both people to have some amount of insecurity and want to go out of their way to make sure the other person really likes them before they let their guard down.
So one of the ways they might see if you like them is to do and say anything they can think of that they think you would like. You would want the other person you’re with to feel secure with you, so that they can let their guard down and be their true day-to-day self (without all the added performances to make you like them).
