Hi TL, Went back and read your thread from the start. One thing I noticed was your H started Testosterone injections not long before B-day. I am 52 and started injections about 4 months before my W's B-day.(10 months ago) I will tell you this, after about 6 months I started to feel different. I lost weight and had physical effects but I also had mental ones. My thinking became clearer, I had more energy and my interest in sex increased (not the intimate side, more the wanting to have the physical experience). Hard part there was my W was no longer at all interested in sex with me (one of the hurtful things she has said many times is that she thinks about and wants to have sex, just NOT with ME!).
I can see how this could change a mans personality, if he was going into an MLC especially. For me, I wanted my W as I wasn't unhappy with my life. Not happy, but I knew my W wasn't the cause if I wasn't. I can see that if he was going into MLC the testosterone could well have speed things up in his MLC messed up brain! Considering how fast your sitch has progressed from B-day to D, it well may have played a part.
Some of the side effects that I was told were less anger control, may become somewhat more selfish, sound familiar? I don't think it could CAUSE a person to go into MLC but I can see how, if they are already starting down that road, speed up the process. Here he is already going into MLC and suddenly his anger level goes up (who to be angry at, well his W of course), he is feeling more selfish and we all know how MLCers are already "all about me"! If the beginings of MLC were already there, these new "feelings" could have helped push him down the road. Is he still taking the injections that you know of?
I don't know how this info can help you but I guess it can't hurt. I will say I have great admiration for you. You have handled your sitch so well from the start and I envy your strength. You have and are showing much grace through your journey! From what I have read of your posts I can say I for one am sure that no matter what the outcome with H, you will come through better for it for sure!
