My girlfriend and I were together for 8 years, she had issues with getting married so we never did.
She had a 13 yo daughter when she moved in, she went through the rebellious stage but we got through that finally.
Two years ago she decided she wanted to move across the country, I did not after some discussion she decided it was right for her and we separated.
Her daughter didn't want to go and asked if she could stay with me, as she was 21 her mom couldn't make her go with her, they've always had a rocky relationship. Kristin, the daughter was definitely closer to me if she had any problems she would talk to me, I'd at least hear her out, then give my guidance and she what she'd do with it.
Kristin was always a slight tease even with mom there, but when mom left underwear and 1/2 shirts were the norm. If she was going out she'd teasingly ask me how she looked, and if I thought her boyfriend would like it, she had a few boys she went out with as friends as I have seen a few here at the house. Well low and behold after going out a few months she ended up pregnant.
