I am so sorry for what you are going through....
When I turned 60 (13 years ago) my husband of (then) 35 years told me (in a very matter-of-fact voice) that I was "too old for sex". (He is 2 years older than I am) He said he "didn't want to have sex with a 'grandmother' " (He thinks because my two children were only adopted by him when we got married, that he is not REALLY a "grandfather" to their children) (I haven't told them......)
Obviously, he thought I was "old", but that HE is a young stud.... He was still working, so I thought his new girlfriend either works at his job or is a cashier or waitress that he had recently met. I didn't waste any time/energy wondering.
I just looked at him in speechless disbelief and I left the room. He moved out of our bedroom to an upstairs bedroom and was ignoring me even more than usual, so I figured he had finally gotten a full-time girlfriend and would soon move out. (I knew he had cheated on me many times in the past 25 years, I just could never prove it)
I spent several days crying so much I burst the blood vessels in my eyes but then I decided to calm down and try to gather some inner strength I didn't even know I had. I decided to try to find whatever I could in the situation that would benefit ME; and eventually I found quite a few!
Was he surprised that I DID NOT yell, scream at him, argue, or beg him to love me, etc.? I don't know.... I decided not to discuss it with him at all....
After several weeks went by and he didn't leave, I said "You don't love me or like me, why are you still here?" He said (in a very pitiful voice = as though HE was the "victim") "I have nowhere else to go". As though I should feel sorry for HIM.
I thought that either his new love relationship had fallen through or that he had jumped the gun in dumping me before he even found a new girlfriend. I don't know....I DON'T CARE....But I'm not leaving MY house! So, here I am 13 years later still here and now married 48 years. Interestingly, he is nicer in general than he was back in the day when he supposedly loved/liked me. WEIRD!
After a couple of tense years, we have settled into a separate but connected type of life. He does his thing. I do my thing. I cook dinner 3-4 nights a week but otherwise he gets his own meals. He retired and took over almost all the chores I used to do: grocery shopping/banking/bill paying/etc. etc. He does his own laundry, cuts his own hair, does all the errands I used to do. I am AMAZED....
I do hardly any chores of any kind anymore! All the little things I used to do for him, no more. Once he realized I was not going to fight/argue/yell/discuss anything about his "dumping" me, he relaxed. It is a bit insane how pleasant life is now. (Although I do have some deep feelings of a desire for vengeance, LOL)
P.S. About 20 years ago, I realized my husband is a covert Narcissist. As bad as this is, it was a relief to FINALLY understand what the c-r-a-z-y s**t he had put me through all these years was about. It had been pure hell & because he is so clever, he has a "nice guy" public persona & everyone thinks he is a great guy!
I know I should have divorced him many years ago (even before he "dumped" me) My age, medical problems, our complicated financial situation, and MY FEAR are my only reasons for my still being here. After he "dumped" me, I started to develop a really calm demeanor & when he says something mean or snarky, I just laugh about it. Insults that used to hurt me just make me laugh now.
Sorry for the long rant! I've been wanting to "tell on him" for a LONG time! LOL!
I have been lurking and reading Mumsnet for about 6 mo. and wanted to comment many times in the past. This post finally got me signed up....
My only "advice" for anyone in a similar situation is to try harder than I did to get beyond the FEAR. I kick myself regularly for not being stronger & braver.
Good luck!
