Me and my now fiancé are expecting twins in five months and he has a 12 year old daughter whom he has full custody of and for the most part she is a sweetheart! However she is jealous of the time and attention that is shared between me and her dad! I am 29 years old and her dad is 39! I have two daughters of my own! Their dad has primary custody of them and I get them every other weekend ! It was really bad at first ! When it’s just me and her , we get along just fine! But when her dad gets off of work or whatever she wants his full attention!
