He hasn't initiated dates in half a year. Is he too busy or not into me anymore?

as the title says, he hasn't initiated dates in half a year. and if he did, it was because I brought up the concern that "we haven't really seen each other in months." he was busy with his last semester of college, working a part time job, and going to church. I tried to understand him but I put in such an effort to be supportive and initiate more that I feel extremely burnt out and am tired. we go to the same church, but we act like were strangers there, he doesn't sit next to me and he doesn't even say hi to me. it's always me that comes to him to say hi. I even brought this up to him how I felt like we were strangers in public at church, but he said he would say hi more, but that did not last long. it has gotten worse. one time we went to the same church class, and after class he just got out of the classroom and did not say goodmorning or even a hi? he literally walked right past me as if I was not even there. [even my ex (who hates me) that goes to the same church says hi more to me than my boyfriend does!] I dunno I am kind of tired. but outside of church, he does text me and ask how I am doing or even update me on his life. we do hang out but only because I asked him out. and when I am sick, he brings things to me or is supportive when I am going through an emotionally tough time. he also did pay for tickets to a theme park in october for our 1 yr anniversary and tickets to a concert in august, but he planned that back in february... so I wonder if he has the mentality that, " oh I put this effort in so i dont have to take her on dates anymore etc?" idkk. the thing that gets me though is that I still have the balls and time to say hi to him or think about hanging out when I have a full time job, serving at church part time, taking a church class, etc.

he finally finished his last course this week, so now I am hoping eventually that he will initiate more but the question is whether I even want to wait that long.

so idk do you think he lost interest in me?
