What can I do if I randomly have anxiety?

I suffer from social anxiety and I pretty much know when I’m get anxiety or what makes me get anxiety but today I woke up good and I think I had pretty decent sleep but as the day go by I started to get anxious and I don't know how to handle it. My boyfriend and I haven’t been in good terms but every weekend we are together. We been together for a very long time and I have told him how our relationship got boring and we don’t go on dates etc. he usually book a hotel for the weekend and we just hang out. But honestly I’m bored of that. He just ends up sleeping early and he only wants to drink or watch a movie. Which it was fun back then but we been doing this for almost 2 years now.
we don’t live together because we need to save up more money but just thinking that I’m hang out with him and things are going be boring because we usually don’t do anything different anymore makes me feel anxious and have anxiety. I kind of want ask him if he want to go see a movie but again it should also be him wanting to go out Seems like he got to comfortable. We been together for almost 13 years.
