I'm planning to book a holiday with my 1yo son. For background story:Me and partner not been on the best terms lately ,he's rather controlling and has narcissistic tendencies but I've been in massive denial about it. So I want to go abroad with our son ,to have a nice holiday and have my grandma (my only family there is my grandparents) meet little one the first time. There are other things need doing while I'm there e.g passport renewal, visiting dentist etc. but mainly the aim is a nice relaxing time just me and baby. He doesn't want to let me go, saying we can't afford it (I'm the only one who works full time,he stay at home dad at the moment ) . He said stuff like "I'm just being reasonable here" but it's not very feasible coming from someone who smokes w**d 24/7 and does not want to work or help me clean or cook after I spend 10 hrs at work every day? I'm tempted to just go anyway but worried about his reaction. Also thinking leaving the relationship would I be unreasonable?
