I need help/advice on creating a balance with..?

the summer and my boyfriend! I absolutely adore my boyfriend of 2 years, and breaking up is out of the question. We're super close and I love that, but this summer I have some major goals that I want to accomplish, so I'll need some more independence! I want to lose about 20 lbs, so I can see if I can make it as a jockey, as well as getting my barrel horse in prime condition for high school rodeo this coming fall. I'll also be fairly busy helping and hanging out with my friend whos 5 months pregnant. So I was wondering how do I create that balance between staying super close with him and also gaining some independence without losing him or making him feel left out and hurt. Thanks in advance! :)
