I cannot stop comparing my current relationship to my last relationship.

I have been with my boyfriend for almost 2 years now. He’s a genuinely great guy. However, I cannot help but compare what we have to my last relationship. My ex boyfriend is what I would call my first true love. I don’t want to be back him with and I don’t miss him, but, I miss the relationship we had together. I miss the banter, the longing to be with each other, always wanting to spend time together, constant affection and communication, deep talks. My current boyfriend acquires none of that. I try to initiate and there is just no reciprocation. He isn’t funny, he doesn’t know how to banter, or have deep talks. I feel like we do not click on an emotional level whatsoever no matter how badly I want to. As a result, it’s making me not miss him when I’m gone for weeks on vacation and I hate any sort of physical intimacy (cuddling, hand holding, kissing, sex). It feels like a chore I dread. I really truly want things to work with him but I’m truly not sure how to go about any of this. I have tried talking to him about it and he makes an effort to change and do better... but it’s just not enough. Does anyone have any advice? I care about him and love him but I’m not *in* love with him. There’s no sparks. I don’t get excited. Any advice is greatly appreciated:( I really want to save this relationship.
