Long Distance Dating Advice Please?

I’ve been long distance dating this man since February. I’ve met his family, all of his friends. He’s flown me out and flown to me. Everything was going well until beginning of May when things started seeming off.

Things picked back up after we talked about things and kinda fizzled (not entirely but there was a change again.) I have not seen him since end of April. He went on family vacation and things picked back up again, texting/calling every day. Then when he got back home, it was radio silence. I have some theories that he’s seeing other women or that he’s worried about long distance.

I would like some advice on a reply. Last week was my best friend of 20 years’ birthday, she passed away last September. We had a phone call last Monday and I expressed how I was having a hard time and he guided my through it.

Tuesday, no follow up but him sending a pic of laundry detergent and some topical drops I don't know. I thanked him Wednesday for Monday’s call and it was a little dry so I didn’t reply. I decided to see how long it would take him to reach out since I’ve been getting the feeling that he’s not as into me anymore. Almost a full week until he called last night around midnight his time. Didn’t answer because I was asleep.

Attached image of the messages, not sure how to reply. I am upset that it took him so long to reach out and check on me knowing that I was in need of support. It’s just getting boring and unless he apologizes and puts in the effort that I need, I don’t think we will work out in the end.
