Me (31F) and my partner (31M) have a 4 month old son, our first child. Since our son was born, a few weeks after, my partner became much quicker to anger, quite snappy, refusing to help in the nights etc, insulting me on occasion. I saw him writing some pretty horrible messages about me one night when he was drunk, calling me a weak person etc, and saying he wished he was single. I confronted him about his behaviour and how I felt I was walking on eggshells around him constantly, and things improved.
Today was a great day too, lots of fun had, no arguments, and then he got way too drunk (full bottle of spirit) and was quite grumpy with me on the walk home from our friends house. I asked him to sleep on the sofa - our baby just had surgery and is in a lot of pain with teething and when he wakes in the night he likes to come into the bed and cosleep - I don't think it is safe to cosleep with someone intoxicated in the bed too. He refused point blank (we have a 1 bed house) and so I said maybe it would be better if I slept at the flat I own (a 5 min drive away). He'd get a break and the baby would get a good night's sleep which he really needed. At first he said fine, and I made sure he knew that we would be back first thing and I would keep in touch. As I was packing up the bag he started swearing at me, calling me names, and threatening to phone the police and report me for drink driving if I left. I had one glass of wine at 7pm (3 hrs earlier) and was not over the limit. A friend of mine knew what was going on and told his best friend, who messaged and offered me a lift to save any drama. I accepted but my partner reacted incredibly badly to this and is now threatening to break up, saying we can't make it work, and calling me a liar, that I'm turning his friends against him and saying he only said he would call the police because I threatened that first. I did NOT threaten to call the police. I would never do that - he's insisting that I did and making me second guess everything. I feel miserable that this is happening just a few days after the baby had surgery. More of a rant I guess but I'm wondering if you think I'm being unreasonable, I'm being made to feel like all of this is my fault.
