Boyfriend problems

Hello,

This has really been stressing me out lately. Ive been in a relationship with my boyfriend for 2 years. He is my bestfriend and I love him alot.

We never fight or argue regularly and im alround happy with the relationship.

Although i take all of these things into account something about him at the moment is weirding me out.

He doesnt say he loves me anymore, he doesnt ever ask me if i want to hang out, he never texts me first, he just doesn’t try.

I cant tell if he loves me anymore, and sometimes it just feels like he is using me. For Christmas he gave me a really nice present, and its not something you would give someone you didnt care about.

I dont know what is going on, i want to mention it to him but i dont want to seem like im complaining about it. For our 2nd year anniversary he didnt even give me a card or anything. He just doesn’t try, he thinks that everything is ok and that he doesnt need to remind me he loves me and why im even in his life.
