To answer some questions ..
I tried to make it so my ex wasn't coming in my house but my ex texted me one day to say "I can see I'm not going to get an official invite to your new house so I'm coming round now".
So I just grabbed DC and went for a drive and replied to ex saying I was out.
Another time, could you say, "you're my ex, so that's not appropriate"
Then my ex showed up another day and was knocking on the door, ringing the bell, shouting up to the window "let me in" saying "I'm bursting for the loo" and all that.
My ex did this. Afterwards, I told him he needs to pee before he leaves the house because he's used up the one and only toilet pass my generosity will allow.
He's never asked again.
But then over Christmas my ex was being nice and kind and supportive around my bereavement which really threw me.
Typical! It's got a name. Reeling you back in. Officially it’s called ‘hoovering’. I’d look it up if I were you; educate yourself. It’s hard to walk into a trap if you've already seen it’s there.
I'm worried about my ex finding out I've lied about dating. I can say "well I wanted to keep it private" or whatever but I'm worried my ex will be hurt. And also that I'll get asked lots of questions
You have to harden here. If you see the world through your hurt exes eyes, or anyone else's for that matter, you will lose your own view on life. Sounds like you already have and you WILL get it back in time, but only if you stop seeing the world through his eyes. You had to, to stay safe, but now you're free and the rules have changed.
He will never release you: you have to do this. It is hard the first time but you could come here and we will support you - the more you practice it, the easier it becomes. And how good and right it feels!
I feel guilty because I've elaborated on some daft lie of what I'm doing today and my ex has asked lots of questions about it and the lies have been spilling out of my mouth and now I've had stomach ache because I'm so nervous they'll find out I'm actually seeing the person I'm dating. And I feel awful that I've lied.
I've said I'm going to a friends house and I'm dreading my ex driving past my friends and seeing my car isn't there.
Yeah, it's not working for you at all, is it? His way doesn't either, so you need to be honest.
"I'm your ex. It is not appropriate for me to answer details about my life because you're my ex. You're not supposed to know."
Expect him to act hurt because he knows that always used to work. When he realises it doesn't, he will eventually stop.
