Fool me three or more times...constant lies

[Spanglyprincess1]

Dp and me have a small baby. Dp isn't cheating , he wouldn't get the time tbh but he has been caught out again lying. It's usually over semi trivial things.
First time was over on a trip buying silver wire for a friend, I asked who he said xyz person. Found out it was for his exg. I went mad as he lied to my face, couldn't give a toss about the ex bit but you don't lie to my face. He apologised.
Then he did it again similar thing - I was pregnant then. I sat him down and said if he ever lied to my face again I'd be gone as it's disrespectful. Said he understood but said did it as worried about my rreaction. I pointed out I was angry about the lying not the thing itself.
Yesterday he did it again, similar sort of thing. Im so sad, he says he knows it's stupid and has been affectionate but I'm just not interested. If he can lie so easily to my face it worries me.
I dont want to be on my own with a small baby as it will be hard and it feels a silly thing to break up over but I don't know what to do as it seems I can't trust him.
Any advice?

Yes, don't issue threats you're not willing to follow through.

I was with a lier once. He would lie even about things he didn't need to lie about, it was exhausting. People like this rarely change, all you can do is deal with the way you react to it and choose where your line is drawn.

Yep. Tbh I don't want to be around him but it Christmas and we have the kids. It's shitty

Liars lie. There will be loads of lies you didnt relause were lies. Ridiculous things from the very minor to the very major they will respond in the same way as there is no difference to them in the mind of a liar. He can’t chNge. Being a liar is who he is. And he is even blaming you, via your possible reaction, as to why he behaves that way. Refusing to be responsible for his own lies. It is absolutely exhausting being with a liar and at he end of the day, youre never a team as you cannot trust them. At all.

Being a single parent is hard but you won't believe how much headspace living with a liar takes. It's a massive relief not to have to worry about a Partner's lies.

I've asked him to leave for a bit.
