Well, I would definitely say he's toxic if he's making you feel like he's being controlling and is "constantly" critiquing your actions.

It's not healthy to not have a life outside of this relationship (alone time, time with family/friends).. and I can only suspect there's a high probability that these behaviours will worsen as this relationship progresses. Major red flags, yes.

I also think if you're needing "help" and posting online, your gut instinct is telling you something is not right about this relationship. Trust it.

Everyone and anyone has the ability to be nice, kind, affectionate, funny, loving.. particularly if they're wanting to control someone else. Make sure his positive side is authentic.
