Newly Dating But Should I Drop Him?

Hi so i’ve been seeing this guy and we’ve been newly dating for about 2-3 months now. Everything was going really well up until the point that he went to Thailand with a friend. We’re not exclusive or anything, but the fact that we’ve been going out on dates consistently, text often, and have been intimate, I find it weird that he never mentioned this trip...He’s been gone for almost two weeks now and we haven’t spoken since the day before he left. I know he’s still there because I see it on his Insta story.

Some of my friends say that I should comment on one of his stories and be like “oh wow looks fun” or just something to acknowledge that I know he’s there but i’m like nahh. I’ve been getting mixed opinions from people too when I ask. Some say that’s a red flag, others say i’m jumping to conclusions and that’s it’s no biggie because we haven’t defined the relationship. It could be either or but I feel like commenting on his stuff could come off needy and I ain’t that girl.

I also feel like if he was serious about this he would’ve given me a heads up, but he also could’ve forgot? Idk. One of my good friends says I should have a conversation before dropping him because it could be miscommunication and could be a good way to spark the convo of where this is going. However, a part of me feels that if he really wanted to talk to me, he would even on vacation if he could post on Instagram. So someone help me please! 😭😅
