Dear Elizabeth: I really feel for you, as I am in a sort of similar situation – I have been having nagging doubts about my relationship, the same obsessive thoughts as yours: ‘do I really love him?’ etc. The thoughts have been so stressful to deal with that I started going to therapy. I haven’t left my partner but I think about leaving everyday even though I really don’t want to.

As Anita said, your doubts are probably linked to fear. Something that has really helped me is a website called https://conscious-transitions.com/. Sheryl Paul talks a lot about relationship anxiety and why do we get these thoughts and how they connect to our inner fears. Also YouTube channel https://www.youtube.com/channel/UCxNjAXPrJm-MI_jr9Er-ujQ

Maybe try to understand whether these doubts you are having are connected to something deeper, and also if there is indeed something in that relationship that needed your attention.

Sending lots of positive vibes your way! Please be gentle with yourself.
