Hi Mums, please can you offer some advice. Never married to ex, together daughter is now 11, we split when she was 7 after i caught him cheating. He earns £116k a year. I earn £21.5k a year. When we split I had to search employment close to school as he was always working abroad and changing the 50/50 rota we set up. I had to take a 10k paycut so one of us here. I love the job that i am in but sick of him telling me well your choice to be there now that he is suddenly here all the time again. Now his role changed and he has been home doing the 50/50 split properly for last 12 months fully and not changed the rota. Things have become extremely strained in last 9 months (before we would still do xmas as a family, birthdays with daughter, mother/fathers day as we had a good relationship. I am happily with a new person 3 years on and he met someone 10 months ago who my daughter hates and has totally brainwashed him) Strained because he has now renounced on the existing verbal agreements around what he would and always paid for (school clubs, holiday clubs etc given his extremely large wage) Daughter has felt certainly for the last 4 months that as dad moved his girlfriend in that her dad has changed and she is no longer given any attention, girlfriend has been verbally abusive to my daughter. I have been trying to get him to agree to a parenting plan since January as this is what he wanted. 26 times i have asked him to respond to my 11 page one after he submitted one (3 page) that was all about changing the financials. Since March i have repeatedly asked for mediation to no avail. Now girlfriend gone back to work and less at the house daughter said it is like my old dad is back. Problem now is daughter has hit puberty, got told off by me for not eating dinner and backchat so went to dads as per schedule and said she dosn't want to come back as i said she can't have her mobile phone. Dad now refused me access for 2 weeks "as this is what daughter wants" and now carted her off down to grandparents without my permission for 2 weeks so i have no access with daughter for 4 weeks. He has also stopped maintenance payments without any notification as of last week. Please can someone help. I am scared about going through CSA as we have 50/50 but his money paid half the rent. I can't afford legal fees. I have no debt or credit cards and my outgoings are literally rent, insurance, car. I have been on 80% for 4 months. I am at my wits end.
