So me and my partner have been together for 13 years and have 2 children 11 and 1 we split when my son was 7 for nearly a year as I found out he had cheated this wasn't the 1st time he had previously cheated when our 1st child was 2 and I had growing suspicion that it there could have been more women. Anyway I confronted him he denied it I showed him proof he said there was nothing in it just a friend which later turned out to be a ex his mum knew her well there was pictures of 2 of them on social media i felt so betrayed by my in laws as they all became really pally with this other woman and i felt they lied too we split up he changed his number so the only contact I had was his mum i never see him for 11 months he continued to see this other woman the year we was apart she went to all his family gatherings went away with them during this time his family called me names he told them stuff about me that wasn't true they used to be nice to me before we split we would go away together they was at my 1st child birth they helped loads we spent Christmas and birthdays together we stayed in there holiday place ever year well when we split they was so horrible to me his mum said some nasty stuff to me called me ugly slagged my family off they never contacted me about there grandchild they used to although they had regular contact still my ex used to take our child every weekend i got on with my life started working had a nice holiday went out with friends then one day my ex dropped my child back home and wanted to talk to me so called me said he was sorry and that he loved me fast forward 3 months from that day and we decided to get back together things where great but his in laws refused to speak to me ignore me in street my partner goes to visit them never invites me they never invite me he does everything separate with them and my children he goes out of room to speak to them on phone he goes to all family gatherings without me he goes to there house where he still has a bedroom at least twice a month with children sometimes more they stay over I stay home alone is this fair? We now have a 1 year old I thought maybe when I was pregnant or had baby they would try and make effort when baby was born they never came to visit we baby was in hospital a week they only spoke to my partner on phone when we finally came home my partner took baby to meet his family without me stayed for 2 days then came back I was left on my own at home baby was 2 weeks old it's been 5 years now and my daughter is 1 now and they still don't speak to me it's Christmas soon and I'm not looking forward to spending boxing day and the few days after on my own again like the last 5 years I have I'm so fed up any advice ?? Please
