Dont want to fuck it up

So I have my boo. And we have been spending so much time together. Its not a bad thing, and I am just so comfortable around him. I have known him for years now and I dont know it just feels right now. I really dont want to fuck it up. HAHA. For real I have such strong feelings for him and Im scared that maybe Im fallin for him too fast. If that makes sense because I have known him for years. We have such a good strong connection. I can talk to him about anything and vise versa. He knows everything about the situation with my daughters father, the ex that took up 3 years of my life, and the drama/stress from school and work. I love that I can tell him anything and he will sit there and listen. Even if Im in the wrong he knows which situations to be like Nichole you know you were wrong or when he needs to just be quiet and be on my side. I do my little wifey part with cookin and shoppin (as far as groceries and hygiene)and all that good stuff. I dont know everything that we do together just fits. So because everything is going so well Im scared it will just get fucked off like other relationships. Anyway, Im just rambling I guess nothing significant really. But really do think that I am falling in love with him. I dont know if Im ready or even want to be in love. So far all I have gotten was a daughter. Dont get me wrong I love her to death but I feel like a failure because I really feel that a child should have both parents in their life even if the parents are not together. But my boo is so good with her. At times I get jealous because she would rather be held by him and not me, and she gives him kisses. I gues all I can really do is take it one day at a time because if not I will probably just drive myself crazy.
