Break in a relationship

Since 2012 on and off .

Me and baby’s father decided that it was best for us to take and break and decide if it was best if we can get along together or apart from each other. We argued a lot over small things and there was no trust . We haven’t been able to get along since last year so he brought it up and I agreed. I didn’t feel heartbroken I’m calm but I keep getting this feeling that time might go by and we’ll be happy alone or with other people . I’m scared that if we get back together we can’t get along again.

I told him that during our break he couldn’t talk to his ex or get a girlfriend or spent hours on the phone with another female which he has done in the past . He said I can’t tell him what to do.

So I’m a big confused about this . I saw a video about counseling and it says that “when in a break you’re still technically together but just limit no touching no sex limit the conversation“

When in a relationship can he talk to other girls ? Just conversations not go and make a girlfriend.

How long is appropriate to be in a “break”?

We were building a house when we were together and not that we took a break he still want to continue, I’m not exactly sure how I feel about that. Opinions?
