Why is he not responding/engaging and what should I do?

I’ve been seeing this guy for just over a month, and our connection—emotionally and physically—feels undeniable. He’s not very consistent when it comes to texting, but fully present when we’re together, Some days, he’s more engaged online, while other times, he’s more withdrawn. During his last visit, he said he mentioned me to his family, which felt indicative. Seemed early, but maybe he’s just someone who shares openly.

Since that night (Tuesday), he’s been distant—
active online but not/barely responding to my messages despite seeing them and posting on socials. This isn’t the first time he’s pulled away; before, it turned out he was just caught up with other things.

He’s opened up about his fear of falling in love, and as our emotional bond has deepened, I sense vulnerability plays a role in his hesitation. We haven’t crossed that final line physically, but the chemistry between us is undeniable. He however recently admitted that I bear a shockingly strong resemblance to his ex-wife—something that both reinforces his attraction (his type) and stirs up unresolved emotions (triggering). Given his past divorce, I can see how this might be complicated for him. He’s even sought advice from close friends and family, which makes me wonder what’s truly going on in his head.

I don’t doubt that he’s interested, but his mix of warmth and detachment makes him hard to read. At times, he says things that suggest he’s developing feelings. He values his independence, so I am thinking about just giving him space.

That said, he has been open about his feelings—just last week, he admitted that seeing a male friend being affectionate with me made him feel some type of way. He acknowledged he had no right to feel that way but said he preferred to express it rather than withdraw.

Am I overanalyzing, or is there something deeper at play? I don’t want to misread the situation, but I also don’t want to ignore the possibility that he’s just not as invested as I am.
