Do I keep him??

My boyfriend of a year and half has progressively (probably over the past 5 months) stopped texting me first, kissing me first, saying I love you first etc... he says I'm just being dramatic when I bring it up. We just went on a break and he keeps saying he needs more time to decide. I know for a fact he's not cheating either so please don't say that's what is going down. Should I give him time or leave him for good, it's hard tho because I love him so much.
