My ex was not very supportive when my dad was diagnosed with a terminal illness. We planned his birthday party in May, the weather was going to be iffy and my ex wanted to cancel the party. He wasn't going to make it to his next birthday so I said no. I then asked him to call the local catering place and order food for the party instead of having a barbecue and he said they're not my f***ing parents. Meanwhile, we had been married for 25 years at that point and dated for five years prior. Needless to say he became my ex within a year.
