My wife of 13 yrs filed for divorce. I work full-time and make a lot more money than my wife. My wife works part-time while being a full-time SAHM to 3 young kids. She’s been doing this since our first was born. I admit she’s the primary caregiver. She does doctor appts, teacher conferences, signs them up for extracurriculars, makes the meals, washes their clothes, etc. I cannot stand the thought of losing my kids. I want 50/50 custody. She wants 70/30 or 80/20 because she says I haven’t been an involved dad. What are my chances of getting 50/50??? In MA.
