I could use some boyfriend advice! thanks!?

I feel the same way..love does that to you. It is very overwhelming. It sounds like you are handling your relationship very well. Don't feel like there is something wrong with you for feeling like this, at least you recognize it for what it is. I would suggest journaling. It is a good way for you to explore those feelings of jealousy and depression, and have an outlet for expressing them. When you look back at what you wrote, you can maybe gain some perspective about yourself and your feelings.
