Well...shouldn't he be keeping you in the loop on the negotiations? After all, aren't you a partner in the business? Why hasn't he included you in the negotiations? This is something that you should be asking yourself. Is he keeping you out of them because he doesn't want you truly involved in the negotiations and be uninformed or does he think you will be confused by all of the hodge podge? Think about it. In business partnerships, generally both partners are involved in all negotiations if it pertains to the business.
Why are you particularly desperate today? Are you basing how your day goes by how you feel about yourself due to the interactions w/him? That's not good. Your day should be about you, what you accomplish or don't accomplish, etc. Whether your xbf bats his eyes at you or gives you a smile, shouldn't be the main factors in how your day is going.
The green eyed monster has you by the tail today. Actually, it's never far away and you need to get a tight rein on it. What happened to all of those tools you have in your tool box to help you? Did you put the tool box in the closet and say the heck w/it? You do realize that you create a lot of your own drama by spinning? Stop, get off the wheel and just be the real you. You'll find that you aren't carrying a heavy load if you just be yourself and learn to listen and know when to chime in on things.
