I've been in a supper happy relationship with my boyfriend for over 4 years now and have no complaints. He treats me so well and I love him dearly. We have had no major issues and communicate well. We've been discussing getting engaged for a while and I told my sister about it a few months ago and since then I've been getting increasingly anxious thinking about our relationship to the point where even seeing my boyfriend now makes me anxious. I can't figure out why this is happening now, nothing has changed in our relationship and he still treats me amazingly but being this anxious has made me wonder whether I should break up with him even though I have no reason why I'd want to. I think part of it might be commitment issues due to my parents super rocky relationship but don't know why that's only playing up now. I don't want this to ruin my relationship and I can't live in this constant state of anxiety. What might help? Therapy has such a long waitlist nowadays that I don't think I'd get a therapist for at least a year.
