I think I should have played here before my invasion,now that it comes to pass. I am trying to keep groups a and b separate so he cannot attack my week group as easily.

White can connect that group to the corner at S9, so no worries about eyes right now. (Ok, so there may be a way for Black to MAYBE force ko if White tries to connect with S9, but it's not realy a worry right now, in my opinion.)

I think the group can connect under no problem. Actually I think at S11, threatening connection and the upper side, may be even better.
My own judgement might be off, but I just don't really see and seriously threatening that thick white group. There are weaknesses at S11, P13, S14. Plus black's last 2 moves can be cut. M12 cut right now gets the eye you were looking at, and push and cut at L12 means L10 is atari.
The K16 group is the weaker of the two white groups under attack, but I'm not sure what's the right shape move for White to attack. H14 and J15 both come to mind.

I have to chase the black group now. I considered h14 but didn't like the weakness in the resulting shape.

I feel like I have been let off of the hook quite a bit here. I can move out to the center easily, and still have an extension to b for eye space. this is not exactly a severe attack. next time I get sente I may play at a. I havent read out all the variations for Blacks follow ups, but it seems really severe at first look.

I'm very sorry but I'm having too many things going on in my life now, and I unfortunately don't have enough time to think out my moves carefully. So I guess it's better for me to resign and take a break until things settle down. Thank you for the game

But why resign? You can just postpone the game.

So I returned after two months of not playing. Let's see how much I've dropped.
I feel I should run here, because: (a) black's move in this area would make my four-stone kosumi group look surrounded and seeking for a connection; (b) I want to separate black from friendly forces

This is the only move. I considered a-d also. a and b are designed to attack the group on the right. If a, W can simply connect under at f. If b, the cap at e is very severe, and I am not sure that even a could kill that group. d leaves me with a thin shape. c may be good later to find some eye space, but right now it is way to slow.

It seems to me that the winner of this fight wins the game. I think this is a dangerous situation. If I misplay, my marked stones may be captured leading to a large white center.

My first impulse is to jump ahead again, but after 88, W connects and leaves the marked stones ripe for attack. If I spend a move at a or b to protect them, W can attack my eyeless group on the left. I might leave the marked stones for now and play something like c. Another option is to try and keep the two white groups separated, but I think the shortage of liberties around M8 make any fighting here difficult for B. Also W could just Cap at "87" and B would need to make life locally.

at S11, threatening connection and the upper side, may be even better.
and 
seriously threatening that thick white group. There are weaknesses at S11, P13, S14. Plus black's last 2 moves can be cut. M12 cut right now gets the eye you were looking at, and push and cut at L12 means L10 is atari.
