Galatea why do you refuse to see that everyone is different, and what suits one doesn't suit another?
Positive male role models who don't happen to be in a relationship with the mother are infinitely better than a bad role model who happens to be living in the same house. We get that you have the absolutely perfect relationship with the perfect man, bully for you, but that is LESS common than "OK-ish" or even poor relationships.
I am single at present, and likely to stay that way now. As a pp said, I'll never say never but I think it's unlikely that I'll find a man who I can put up with or will put up with me. I've been in love in the past but it never worked out, and looking back on things I can see that however much I may have had that feeling, it really wouldn't have worked out as a permanent arrangement.
I like my life the way it is, it suits me. I have people I love dearly, including an ex-DP who I now look on as a brother and he sees me like a sister, blood family, other friends, my cats. I can do what I want, when I want, with who I want. I don't feel like I'm missing out on anything. I DO know I'm missing out on having to compromise to suit someone else, take their wants and needs into consideration, plan my time around them.
I am happy the way I am, you are happy the way you are. Other people are happy the way they live. Just accept that please.
