My partner and I bought a house together. He already has a house he lives in elsewhere in the country and he used money from a holiday home he sold to invest in this second house which is my only home with my 2 children. This meant there was a bigger house with a bedroom for his daughter to stay in. We agreed to keep the house until my children were 18. The relationship has now ended with a year still to go before my children have left home. We haven't spoken since February. He sent a couple of upsetting letters which have left me feeling distressed but has agreed to honour what we had said. He turned up this morning out of the blue and parked in the drive while I was out. He then entered the house with his key while my daughter was in alone then stole the back door key. He lied to me about stealing it and I had to be very insistent to get it back as I wouldn't have been able to lock the back door. He said he wants to keep the relationship but I have found this behaviour upsetting and invasive and I don't feel completely at ease in my home. I feel very trapped and upset by it all and am trying to keep things steady for another year until my children finish sixth form. Would you feel /do the same?
