I told him I loved him after about 1.5 years, and he didn't say it back - he said he's not great at saying these things, and left it at that. That was fair enough. I've never said it since and neither has he. I'm curious now to see does he love me though, not necessarily that I want him saying it all the time; it's just sometimes I feel the relationship is not a priority to him and I feel if he can't say he loves me after 4 years, there's something wrong - am I right or overthinking?
