Potentially another woman or not interested?

The guy I’m dating lol idk things seemed to have been slowly declining communication, meeting up, sex, etc but I could sense it slipping and I mean everything

I asked him Monday if he wanted to meet up Thursday…. he did read it but never responded he ignored it changed the subject I was like ok then 🧐 I mean he didn’t forget lol he seen my message again when he texted me

Cos it was like

Hey are you free Thursday I was thinking we could do something

He read it

Then seen it again to text me Hey beautiful

Today he was all babe I’m sooo sore n I miss you

Soooooo I said

You mentioned you had some free time this week and I tried to set a time to see you and you keep ignoring me, if I had to guess I don’t think you miss me all that much. Am I reading into this right?

He read it this morning and texted me this evening doesn’t help I’m busy 🙄

I’m just like fuck this guy why would I wanna be with someone who doesn’t give a shit about me….

Like I said everything has been slipping through my fingers these last few weeks this isn’t a case of girl he’s busy no this is a case of something is wrong and he won’t talk about it if I ask

Curious on his behaviors could it be he lost interest or someone else?
