Is my boyfriend using my mistake to further abuse/control on me?

I tried to leave my boyfriend after he physically abused me once and I started talking to someone else (for 2 days). I really thought I was done. But I fell for his lovebombing and now we’re back together. But he knows I was talking to someone and I feel like I have no privacy. He wants to know where I am, what I’m doing, who I’m talking to. All. The. Time. If I touch my phone, he’ll try to get me off of it or question me about it. If I tell him what I’m doing but switch apps and he sees, he accuses me of lying. He always insists that I “must be talking to someone” or “my other boyfriends”. He questions all my friends. I had location shared before we broke up and just let him have it again but my phone is glitching out and he mentions checking it sometimes. If it doesn’t work, he insists I’m turning it off. It’s been 2 weeks and he’s getting worse too.

I know I made a mistake but I planned on never taking him back and this feels so extreme. I want to leave but love bombing is extremely hard for me because I grew up with a dad like him so I always fall for it because it gives me hope like my dad did. I’m in therapy but that’s not an overnight thing. Idk what to do
