I feel sometimes that I'll never be happy with someone. I'm 30 and have a beautiful 5 month old daughter. I'm not with her father anymore. I've been single for over a year now and not that I've been lookin for someone right now. I just feel I'll be alone for rest of my life with my daughter and I really would love for her to have a sibling (not right now) because I'm an only child and I do love it sometimes. I've always wanted to have that sibling bond. sorry to vent a little .
