Has he lost interest and simply doesn’t want to tell me ?

To make it short, I’ve been seeing this guy for a month and a half and we’ve been going slow, but I’m starting to develop feelings. However, I feel something might be off. I’m not reacting for now, I will just let him be, but I don’t wanna invest in this anymore if it’s gonna end up hurting me. I just wanted to hear some people’s perspective to know wether I’m overreacting or not.

It was very passionate at the start, he would constantly text me, and he was so romantic I just went with it.

For the past two weeks, he’s been a bit more distant. I think mainly because he has a tough job, and well he has a life. He’s been giving me slow replies, leaving me on delivered for hours and hours, sometimes only texting once a day. Yet again, doesn’t mean he doesn’t like me but I found it odd.

We saw each other two days ago, it was nice but he acted very angry about his job. I even saw his parents who were super sweet to me (he lives with them), but when his mom started complimenting me he shrugged it off and it made me slightly uncomfortable.

Anyway, we had a nice night at his place still. He was very tired so it wasn’t that eventful, but he was sweet nonetheless. He even confirmed he wasn’t seeing anyone else, so we’re basically exclusive now. Or so I think.

We barely texted after that, I was very busy anyway. But today I replied with a quick text to him talking about his day, asked a question on what he was getting for Father’s Day, and he simply left me on read all day. He was online after that, still didn’t reply. And even though he might have gotten caught up with his day, I find it a bit odd… because at the start he would make the effort to quickly respond, he would actively say he was thinking about me and all that, so it feels like when he wants to, he expresses his interest clearly.

Anyway, right now I’m just thinking he’s not that into me. I’m not gonna react or anything, I’m just gonna let it be, but it hurts me to think it’s not going anywhere. And I really don’t wanna hear the typical excuses as to why he doesn’t feel it anymore… It’s draining to think about it and I don’t know if being rational here means interpreting his behavior as a loss of interest.
