My husband is as far as I see it the other half of me, we share pretty much everything and make decisions jointly. It’s part of being a couple.
Whilst I think it’s great that you’re both obviously deeply in love still, the fact is the two of you are not an entity, you are two separate people who for various reasons choose to spend much of your time together, live together and share a bed together. If the unthinkable happened and he died, you would not suddenly cease to be able to exist yourself.
I think maybe my deep seated feelings come from my hatred of many couples seemingly becoming inseparable once they get together. I’ve lost numerous friends to their BF’s/GF’s suddenly stopping them doing anything fun (like riding bikes, going for a night out etc.), insisting that everything be done as a couple, and all individualism destroyed. And before you accuse me of being sexist, I’ve got female friends that this applies to about their boyfriends too. Whilst it is healthy to be in a loving committed relationship, it is also healthy to have your own hobbies and interests separate from one another.
