Frst of all I have 3 children from previous relationships Son 14, Daughter, 12, and Daughter 3. When my SO and I met my youngest was 18 months and he has become the only father she know. My SO has 2 children from his previous marriage SS 11 and SD 9. BM is very controlling and hard to deal with. Originally SO had children 3 weekends a months and 10 weeks in the Summer. BM now has that reduced to every other weekend and 6 weeks in the summer because the court agreed the children needed to be in every activity under the sun which, bring me to my issue.
