First of all I'd like to say thx for not being too bias...Yet I still must say my side of the story and point out common and informal game rules in a 5 step answer that will krush your clueless rambling...
1.) The FEEDER (Me) decides on what that money is used for, there is no arguing this, and it is common practice for feeder to call the shots. The money is not yours since you were incapable of winning alone therefore you have forfeited decision making in exchange for feed and for the overall success of your team. That means if your feeder says cut your losses and move on, you LISTEN!
2.) Sin's 101 also dictates that you NEVER engage titan unless you can kill it since any attempt would only make it stronger by leveling up which you did by suicide on it deliberately and getting it up to level 5. Which will in the long run hurt your team because we will have to engage and kill a level 5 titan and to do this will cost us consideberately more ships and resources than had you not leveled it up.
3.) Suicide position is a double edged sword you are draining vital resources in a goal not to hold out but to simply buy your team time. It is a fact that in a "skilled" game you cannot hold out suicide spots. Not even the most experienced (Slayer/Doci) can do this with a 2 frontal assault of skilled players, So the question is when does it become reckless to feed you 100 credits per second to simply have it wasted leveling an enemy titan? The answer is the moment you stop being rational which was pretty early in this game. Like you said I did feed you early on, and I would of kept doing it had you not lost and the situation turned hopeless.. Sure you bought some time but you didn't do it alone. You effectively tied me up to hold a single planet out of some personal grand desire to not lose to kok which wasn't very team oriented of you.
4.) You have a choice when in suicide spot, you can relocate this is always a tactical option and sure your opponent may chase but after 2-3 planets they will turn back and go finish your hw, if you were smart you have upgraded your hw with 7.5k health which should give you a good 10 minutes to rebuild elsewhere.
5.) Lastly I have one word for you RESEARCH this is the most important aspect of why you should have listened. You can hold out well during early game because with 1-2 planets can research the basic civic/military upgrades but when you are an egg without many options or slots your opponent will quickly surpass you in both military and civic research. Making his fleet extremely more effective than yours, not to mention he will have a wider choice of more powerful ships to counter your 2nd rate fleet. Not only will he be able at this point to get more bang for his buck but he will be able buy it alone since he has been colonizing while keeping you under siege.
I'd also like to point out that had your opponent been someone else and not arrogant and noobish kok you would have died rather quickly. He had an easy victory over you but squandered it by not using his surrounding planets as he should have. He wanted to beat you only using his hw without any other planet which is pretty arrogant but he gave you a run for your money since you got 23k credits, 7k metal, 4k crystal. Kok on the other hand received NO FEED or support from allies other than culture. The bottom line is you got whopped pretty badly with feed in 1 on 1 and you were arrogant and clueless enough to refuse advice from the guy feeding you. After taking a closer look at the game I don't know what is lower your skills or your manners. My advice for you is to learn to cooperate with your allies because if you don't change your attitude, I see many more rambling posts in the future about your shameful lack of skill, knowledge and humbleness.
