As someone who is avoidant I have to ask why "living an unblended life won't work long term". I was involved in a similar relationship and he had the same feeling about it (we broke up over something else because I was trying to follow his lead, so we did get married and live together). But especially this late in the game (age wise) I'm wondering why the anxious or secure person feels like there needs to be marriage or cohabitation. Any thoughts you can share would be helpful!
