Been with my boyfriend for years now, we are both in our mid 40s, I am childless and he has an 8 YO DD who he has half the week. I see him a couple of times a week and I have always been indecisive about living together, which he would like although he is not naive that it won't come with challenges, so he understands my reticence and hasn't insisted. I like his DD but reality sort of set in and now I am fearful of regretting such a commitment. Kids live at home longer nowadays and I am basically signing up to maybe ca. 18+ years of having to share my home (which i view as sanctuary plus I WFH a lot), with his DD. It could be a nightmare, especially school holidays. I need to decide whether to move in together and pool our assets. He has a small flat so we'd need to get somewhere bigger but the most we can afford is a small 3 bed flat... Should I bring our lives together, or, live alone indefinitely, or, end it and be single. I love him and always imagined getting married and living with a husband. I feel like if it doesn't work out living together our relationship may be over too. Looking for advice from stepparents I guess or partners of stepparents. AIBU to fear living with stepD?
