My boyfriend is great. He loves me and cares about me. But lately, he's been off. He doesn't send me long messages claiming his love for me or give me small surprises anymore and he even didn't get me a birthday present (he said he ordered one but it's been a month and a half). He still says I love you and I really believe he does but I just want him to do the things he used to. I don't know how to bring it up without him feeling like I don't want to be with him.
