Am I being a pushover or is this genuinely something to be concerned about?

So I’ve been in a pretty good relationship for the last 6 months. I’ve never had issues with him lying or cheating, he’s been very honest about everything. Weve has a couple fights (we are long distance so the majority of them have been from that). In the beginning he was very lovey dovey, always wanting to call me or face time me when he got off work, always sending text messages saying I love you or I miss you every other text. But then weve has fights and it seems like after that he just seems distant or closed off, wanting to try less after each fight. His reassurance started to become less and less... lately it seems like I’m the only one putting in effort to talk. But when I bring that up to him, he gets offended or upset because he says he does so much to show me he loves me and that it still doesn’t work. The past few nights when he’s gotten off work, he hasn’t said anything to me. If we do have conversations they don’t last very long. Tonight he got off work and just sent “😂😘” in response to a picture I sent him way earlier while he was working (which I know he can’t text at work). Anyway... I just have never had a relationship this long and neither has he, so I don’t know if this is normal and he’s just comfortable with me now or what. I guess I just feel like if he really wanted this to work and really cared that he would communicate more. Instead he just goes to bed sometimes without even saying goodnight and it seems like that happens a lot more often than not. Am I being dramatic?? Is it wrong of me to want someone that is excited to talk to me? Especially because we are long distance.
