<human>: So before my boyfriend and I started dating a few months ago I was already extremely happy. Happier than I had ever been. Having him show up in my life has only made me even happier. However, sometimes we go a few weeks without seeing each other because we are both busy and we don't live in the same city and I find myself thinking about him a lot and sometimes it does make me sad and unhappy. It makes me feel like I'm becoming dependent on him for happiness which I really don't like. It's not like I'm sad all of the time when I can't see him. I do a lot of fun things on my own and with friends and do experience a lot of internal happiness but I just know if he wasn't in my life I would be so sad and I would miss him so much. I am feeling myself getting attached. Is it normal to feel this way? I'm 21 and so is he but this is both of our first relationships. I don't want to feel like I need him in my life to be happy but it's starting to feel that way. We've known each other for a year and had feelings for each other for a long time before we started dating and we've already told each other that we love each other. And I really do love him. I guess I'm getting a little worried about how attached I've become and how I could potentially get really hurt in the future. We talk every day and a part of me wants to let him know that I need a few days to think and not talk to him but I really don't want to confuse him or upset him by asking that. I just feel like I need to put some distance between us to make sure I can still be happy on my own.

Can you summarize the given text in a few sentences?
<bot>: How can I stop deriving a lot of my happiness from my relationship? Is it normal for me to feel the way that I do?
