Should I let him go?

We’ve only been dating a month.

Everything was going well, he called texted and FaceTimed all day everyday.

In the last two weeks it’s lessened.

In this month I’ve only seen him twice and never by himself, once I drove to him and once when he was out with friends. Never really made time to spend QT.

Last weeknd he changed his number and didn’t call me to give it to me for 2 days.

Said he had a death in the family. I get it but 2days? Keep me wondering for 2 days???

Now he’s been dry, doesn’t flirt nor flirt back, doesn’t want to call.

At this point since the beginning I’ve been so in my head I think it’s time to let go and maybe change my number. Am I overreacting??

Edit: Changing my number is the only way I feel I can move on. Not expecting his calls or texts anymore. Knowing it’s done.
