Need advice

[Jordansmummy]

This maybe a touchy subject but has anyone else has a partner who is facetiming an EX but lying saying that they don't know how that persons number got in their phone and that persons texting him and he isn't replying but you have seen the messages, has anyone tried hacking their phone to get the proof you need?

why do you actually need proof?
If you can’t trust this person then it isn’t a relationship worth staying in anyway.
sorry

I need proof to get him out the house, he is denying everything, saying that my mind's play tricks on me and in seeing things when it comes to the messages - he left his phone opened on her message was showing up and she asked if they can facetime and asked my OH to go out the house because I was home with the 2 kids

Who owns the house? How would you having proof get him out of it?

My name's on the tenancy but he says I have no proof to kick him out and that it would be my fault for breaking up our family, my kids are 1 and 4

If your name is on the tenancy you don’t need an excuse to ask him to leave.
Next time he leaves the house, pack his things and put them outside.
Have a friend/family member with you for support, and ideally the children elsewhere.
If you expect him to be aggressive, phone 101 and let them know you expect him to cause a disturbance, so if you need help later they’ll come promptly.

Good luck x

This. You don't need proof. You can make a decision and carry it out, without evidence.

Just to add - I spent 3 extra years with a waste of space ex because I didn’t have proof. He could always talk himself out of any situation.

After I eventually dumped him I found out he’d been unfaithful multiple times.

you don’t need proof of anything to end a relationship, being unhappy is reason enough.
