WilliamDupree, you did not lose anything.  that was not a friend, but a 'fair weather friend';  in other words, someone who would be your friend ONLY if you did things their way instead of observing normal protocols.

two consecutive moves is not grounds for a draw.  repeating the position the third time allows one to claim a draw, but it must be claimed, it is not automatically awarded, no matter how many times the position repeats.

hope that clarifies things for you.

If you're in a winning position, a draw is out of the question. We have to take our losses and learn from them.

NO,these type of thinking comes in theory only.

Actually the scenario is an interesting one.I had achieved a won position against a very keen player who pointed out that they were exhausted and asked me to concede a draw. I thought about it and decided: [1] my position was won and that fact should be recognised [2] psychologically it might benefit my opponent to just fight through.

My opponent played one or two further moves,accused me of making two consecutive moves and then resigned.Subsequently  'Friend' status was cancelled and I was barred from further communication.

No, just finish them off, then ask them politely why did that.
