First?

Probably better to let go when you're emotionally ready. And make sure to take the cat with you!!!

Maybe his relationship should be with the cat

Perhaps its time to reassess your relationship. It doesn't bode well if he is more invested in the cat than he is in you.

You already know what to do, you're just waiting on somebody to say it. He doesn't value relationships, but you do. It's not going to work out in the long run because you can't change him. It's better to get out sooner rather than later.

I Kinda do agree with the top comments. That was not smart of him. There could be an off chance he was trying to see how you feel about furthering the relationship. But if it's your cat, if you leave him, take the damn cat!!

Marry him and have his baby. That will fix everything. (Psssssst.... No it won't.)

Well, at least you found out sooner rather than later that he's not interested in making it last. As soon as you're emotionally ready, cut the ties and bail. If he doesn't see a point in being together long-term, that's his loss.

Ask him what's wrong about the relationship, he clearly seems dissatisfied with something or some things.

One thing I've learned about men in all my years of dating. If they say they feel that way, they ACTUALLY FEEL THAT WAY. It's not that he's grumpy. It's not that he's scared. It's not for any other reason. Sorry, but if you want a relationship that's going to the next level, it won't be with this dude. Dump him.
