I’m obsessed with my boyfriend Watch
We have so much going for us so I don’t know why I can’t just look to the future and be excited. Why is this happening? Any thing I can do to go back to my old carefree happy self?!
So you could try doing a bit more by yourself/ with other people.
Likewise if you currently don't do much together or used to do more you might be feeling insecure because of that. You could try to make a bit more time to do stuff together or to remind yourself of what you DO do together (yes I said dodo). There's a lot of truth to the "honeymoon phase" and how difficult it can be getting used to the changed dynamic once you've gone from dating and being a cute novelty to eachother to being an everyday part of each others lives.
You could also try to have a think about anything else that may have changed in your relationship or either of your lives to see if that's triggering any subconscious feelings and insecurities.
At the end of the day he's with you now. Any past relationships don't matter cos he's chosen to be with you. Worrying about the possibility of separating at any point is just going to make you more stressed and put strain on your relationship cos you aren't fully happy/ secure. Yeah there's always the chance that even people who've been happily married for 50 years will break up, but at the same time unless you've got any reasons to worry that could be you there's really no need to consider it.
I hope that helps.
