39yo, 5'6", 141 lbs, BF 20.5% LTR is 40yo. 2 kids.

I had plans tonight to go out to a class (something I’ve been doing to get out of the house more and have more hobbies). My LTR texted me midday and says that after work she has to go check on a friend who was saying some potentially worrying self-harm things. She says she’ll try to be back by the time I need to go (as I have our younger daughter with me and somebody needs to watch her).

I tell her that timing wise there’s no way she’ll be back in time. I ask if she can meet me first and I can have our daughter go with her over the friend’s house. But I don’t hear back from her until she’s over there, leaving me with no option but to stay home with our daughter.

Now I feel like I’m mostly overreacting and that I should just let this one go due to the circumstances, but also I can’t help feeling like she’s putting me at the bottom of her priority list. If this was a life or death situation, she would have left work early, which she didn’t. She also had time to pick up our older daughter. But just didn’t have the time to work something out with me so I could keep my plans.

Any advice on how to handle? Half of me feels like I should just stfu and let it go this time and the other half wants to make it an issue.
