Even among real-life friends, team cohesion is difficult to achieve. Project management cannot rely on hobby and self-motivation alone, which is why a lot of online projects fall apart. There's a degree of professionalism and disciplinary actions required to keep team members doing what they are supposed to do.
I would suggest working on your own, then publish a demo with your programmer's art. If there are artists interested in making your game look better, you'll hear from them. If not, you can always pay somebody to do it for you. I actually prefer purchasing for services than relying on friends. When you purchase for art, you can specifically define how you want it to look like because you pay for it. Friends will have their own ways of doing things, and sometimes they want certain unfavorable demands, such as 10% of profit even though all he did was the splash screen. Another reason why teams fall apart: arguments.
Just because you found some people to make games with does not mean all of you will hold hands throughout the project. You will have different opinions about many different things. How the game look like, how it plays, what type of music it should play on the title screen. It can be frustrating to mold these opinions/arguments together into one solid product. Then there's the dreaded miscommunication. People don't always see things the way you do. I am sorry to ruin it for you but making games isn't as fun as you might think it is.
If it's an RPG, don't feature 10-year olds beating the crap out of gargantuan dragons with their white/black/red magic shit. Don't insert guns as ancient forbidden technology into a story that begins with sword and arrows and magic. I swear, all these RPGs out there feature the same shit over and over again. No, I don't want to see "Heal" ability in my White mage skills. Why does Heal always have to be "White" magic? Why is there "Heal" at all? And fuck Paladins.
If it's a FPS, don't feature handguns and shotguns as your first weapons and rocket launcher and lazer-pew-pew as your later weapons. Fuck, why don't you just give a rocket launcher at the beginning of the game just so you can blow shit up for a while and give laser in the next mission to make holes with? I don't give a fuck about FPS stories, so you can be creative there or stick to the old blowing-up-aliens storyline is fine with me. Just be creative with the weapons. And I don't want to see moving platforms and be jumping on them on FPS. I can't see where my feet land, and I hate to guess.
I think it's been brought up before that there are legal loopholes that benefit Amazon in the AZ App Store contract. IGDA and quite a lot of other people have made noises about this since the first time the store opened. It benefits them more than it benefits developers. The fact that they signed up for it and complained that AZ took advantage of it is recklessness on their side.
Btw, after knowing about the legal loopholes, I basically uninstalled Amazon App Store App from my Android. I support developers. I don't support corporations trying to cash-in app-store bubbles.
I actually understand why she said "but I love you", but actually did the opposite. She actually cares about you, but she's not sure if she wants to be with you. She doesn't think you are hot enough. You are not exciting enough. In other words, you are boring now, to her. See, a woman can care for a guy but not sleep with him. Are you friend-zoned? Not really, friendzone is worse than that. Consider that somewhere in between, which also sucks, btw.
Do you have any chance of going back to her? Yes, if you play your cards right.
Am I suggesting you to do that? No. Don't ever try to go back to your ex. She'll come to you when she wants to.
Now, back to you, how do you cope with the loss? Nothing much you can do. Do other things, date other women, eventually it will wear off. Try to be more interesting, develop new skills, new groups of friends, and have some vision to your future (which doesn't involve her).
Even if I hire someone else, I wanted this kinda rough, cartoon look. Or make it look like everything is in a sketchbook. Rough, grey and white, no shading basically just outlines.
From my experience, it's always difficult to communicate artistic view such as this to an artist. Self-taught artists tend to develop their own style. So they will be good at certain styles -- their styles -- and may have difficulties drawing in other styles.
It's my style when I draw free hand, believe it or not I'm actually a decent pen/pencil artist, I'm horrible with the mouse though.
Consider investing in a tablet. Worth every penny. Bought a Bamboo for ~$80 4 years ago, and I still use it.
