A little complicated

I have been with my boyfriend for a year and 4 months. I love him to death, he’s the best thing that has ever crossed my path. However, there is something missing. He isn’t affectionate at all! I try to not show that it hurts me, but every time i tell him i love him he doesn’t say it back. He says that he can’t say it, but he can show me. Which he has. Another thing, in super cheesy and somewhat clingy. He isn’t at all, if i don’t make an intention to hold his hand he wont. He wont ever be the one to lean in for a kiss or a hug. He won’t even take pictures with me. Im always the one giving him all my love and attention. Wish he could be the same, then again this is the person who im in love with. Sometimes this affects me, and other times i accept it. Sometimes i tell myself, “Maybe one day I’ll find someone who wants to kiss me, hug me take pics with me. Then again, i cant image anyone else because im in love with this person and i cant imagine myself with someone else. 😔

Can anyone else relate? Or advice me? Thanks.
