Am I wasting my time on someone that might take forever to realize that I’m the one?

This is too big a question for your gut instinct.

Use your head and without “but I love him” delusions make a list of what you really need in a partner to be happy in the long term, starting with “is he good to me?” If it’s not him, leave.

If it might be him but you waited so long that this is no longer a “short term” issue, put him on notice & leave no later than 2 months if he can’t change
