ExH and I have an agreement made through mediation that he can phone to speak to DS age 4 and talk to me about DS on two evenings a week. (We have this arrangement as he was abusive and after we separated was phoning up to 40 times day and was often unpleasant. Police were involved and had a 'talk' to him). There is a lot of background as ExH has lots of issues and has caused many problems for me and upset DS a lot. He sees DS for half a day each weekend but hasn't done for the last two weeks at his own choice.
ExH can be very pleasant to DS on the phone and DS enjoys talking to him. However ExH is frequently short tempered and moody with me. He can be very abrupt and swear at me for the slightest issue but mainly when there's no issue at all and he's misheard something I've said or I haven't answered quickly enough or he perceives I've used the 'wrong tone of voice' with him etc etc.
This evening ExH managed to swear in earshot of DS about a relative (one who DS loves). I ended the call (I always do this when there's any swearing) and told DS there was a bad signal.
Just wanted some perspective on this please. DS likes telling his Dad all his news however I find most phone calls very unpleasant. Does anyone have any thoughts or advice please.
