Hi. I’m 28(F) and my fiancé is 31 (M). We’ve been together for 3 1/2 years. A month ago, my fiancé, let’s call him Paul, asked me to marry him. We both wanted to bask in moment and not plan anything until now. Paul’s sister is 3 months pregnant, we have known about the pregnancy before our engagement. Paul’s sister is due 2 months before our chosen wedding date, the end of February. I work in education so it’s not exactly easy to take time off. We are choosing to have our wedding at the end of May. I’ll be on summer break and my dad would still be alive by then. About a year ago, we received devastating news that my 80 year old father (my parents decided to have me last minute) that he has hydrocephalus. Due to the symptoms, insurances and the time it took for tests to confirm all of the things, the surgery is too risky due to how much fluid is in his brain. My parents have gone to four or five different doctors and each refuse to operate. Although we were given different timelines, I want my dad to be able to remember the day I get married before either A) the fluid permanently distorts his memory and mood. The latest scans show the fluid just now starting to cover his temporal lobe. The majority of the fluid is at the back and bottom of his brain. He has lost all mobility in his limbs. Or B) he dies. Due to money, we are planning to have a backyard wedding at my parents house that way my mom is not stressed about anything regarding my dad and travel for them is not a major issue. Since we sent out invites, Paul’s siblings and mother are upset that we didn’t include their opinions on the wedding date. Paul and I chose a month and day where there are little to no anniversaries, death anniversaries, births or other special days. The drama is coming from his sister who believes a May wedding is too soon after her birth, and Paul’s SIL who hates my guts. (Story about that in comments). Anyways, I feel like my future SIL is playing off of Paul’s sister’s feelings. So am I the asshole?
