figure out if my boyfriend is "the one"

I am hoping there is. I know no relationship is perfect, I know people have bad days, and I know that whether I like it or not I will one day look back and say “I wish I hadn’t said that”. I hope the last one doesn’t happen, but I know sometimes I put my mouth before my brain. We have been together for 10 months, and I think we are getting a little stagnant. I wish I knew how to spice things up or if it was even worth trying. He has a 12 month old son from a previous relationship and I raise him as my own because I’ve been a part of his life for over 75% of it. I know most every woman on earth knew how to read her significant others’ mind…I don’t know why we can’t – although, I am scared to think what I might find out. Am I just insecure? I have never really been before. Well, I’m not when I’m single…relationships change me…and I don’t like that. He fell in love with the single me; so, why should I change that person? I have ADD, and I think it is kicking in right now. I just want to know if he is in a “funk” right now or if we are about to be over.
