Advice sought.
My partner split with his wife 4 years ago, we knew each other when the divorce was happening and we started our relationship not long after they split. The EX wife has never forgiven us for getting together so soon. She refers to me as the family destroyer, claiming if it hadn't been for me they could have gone to mediation and work things out, something my partner refutes, he always told me their marriage had been dead for at least 4 years before he left her. They had 2 children together who were 10 and 8 at the time of the split and she had a son from a previous relationship that was then 19. My partner was very fair in the divorce, signing over his 1/2 million pound house that she had put nothing into, gave her a lump sum of 85K and paid top child maintenance and voluntary spousal maintenance even though his solicitor said he was being over generous, he said he wanted to ensure her and the kids were looked after financially, something i admired about him. He shares joint custody and the kids are with him every other weekend and certain nights of the week also. However the issue i have is she poisons the kids against me, tells them they are not allowed to speak to me, they are to call me THE WITCH, she threatens them that if they have anything to do with me and she finds out they will be traitors and disloyal to her. She constantly bombards my partners phone with abuse directed towards our relationship and me in particular. She has flatly told my partner the kids will never accept me and she will not let them stay in his house if i am there, which resulted in me not being allowed to stay at the partners house on days he had the kids. Now my partner tells me that he wants me to move in with him but we have not ever been able to introduce me to his kids because the ex will not allow it, and the kids are scared of upsetting their mother so hide if i try to 'pop by'.
Now she is asking my partner to go round and fit up furniture she had brought for their sons bedroom and is inviting him to go to a family day out for his birthday but i am not allowed and during a recent telephone conversation she screamed Fuck off down the phone at me after asking my partner if i was in teh room.
My partner sees nothing wrong with helping her with the furniture and going out with them for the birthday celebrations despite her behaviour towards me.
I am upset and told him so, and he is now angry with me, saying this is for his son.
would appreciate advice... am i being unreasonable?
