Need perspective!

I am quite independent and manage most things myself. I look after most of the house stuff. My partner does some regular things and is not good at planning with his ADHD. He is always okay if I ask him to do something. He also said he leans on me when it comes to planning as it’s not his forte.

We wanted to start trying for kids and as my iron is low we decided it would be good to get an infusion that GP recommended.

So I booked the appointment and he said he will join me. I was like, I can manage. But his response was “no, I am coming with you. I will take you”. I was really happy that he want to be engaged. On the day of the appointment, I plan my day to make sure we are able to head out. He doesn’t talk about the plan or when we have to head off. Closer to the time he comes out of his room and says he could use a focused day at work. I lost it.

I was so furious. I told him it was not okay to not take action to his commitment and that I never asked him to join me and that his words won’t mean anything if they can’t be coupled with actions. He started asking if I want him to join. I said hell no. Not after this conversation. F off and left and got my infusion.

It feels quite personal now. I am now sitting thinking is this a good relationship? And do I want a kid with this person. I had a failed long term relationship where I didn’t read all the signs that were there since the get go and now I am a bit freaking out. Am I overthinking?
