If you see this @Pinkswans I want you to know that I am both crying and raging for you at the reception you have had from far too many of the PPs on hear today.
I read the whole of the first page of this thread and couldn't take any more of the responses you were getting, they literally made me feel sick, so I switched to just reading your posts - some of which obviously had quotes of what some of what a PP was saying to you.
I'm a grandma now, but I can still at least partially remember the exhaustion of the baby years, and I honestly do not know how you are coping. I thought that my first baby was difficult, but she was a doddle compared to your DD, and that wasn't because I was doing anything better than you are, I was just a lot luckier than you. I was also lucky that my DH wasn't the sort to out drinking with mates, well until he left me for someone else, but that is a different story, maybe for another day.
It seems to me that you have two overwhelming problems, and quite a few other ones, but I think that the two most overwhelming ones you have are obviously for the first one, your utter exhaustion, and I think your second one is loneliness. I think that you are missing your husband and partner so much. From what you have told us here, he seems to have just disappeared.
Yes, you can still see his body, you might even get to sleep beside it for parts of the night. You get to hear a voice that sounds like his voice, but he doesn't seem to actually be there in the consciousness that you knew and fell in love with. To me it seems that the partnership part of your relationship is on hold - but hopefully not for too long, so please don't give up hope about you two reconnecting again. An "after you have had children together" relationship can never be the same as a "before you had children" one. But hopefully if you both want it to, and when you both have the time and energy to devote to it - which unfortunately will probably not be for a little while yet - between the two of you, your relationship can grow into a stronger and closer relationship than you ever had before, afterall you now share the two most precious things in your world!
I think that your DH is being very selfish at the moment, and I also think that he is probably totally unaware of how selfish he is being. It is possible that he is also overwhelmed with having two little ones, and a wife who is too tired to give him the attention he probably still expects to have. I don't like making 'general' statements, but I will risk it here, I think that an awful lot of men do not understand (even after their children are born) that life will never, and can never, and even should not ever, be the same as it was before their children came along. But I am not making any excuses for your man, or any of the other men who have their noses put out of joint because they are no longer their wives main concern.
You quite understandably want your partner and hopefully, best friend too, back. You also hopefully don't expect him to be exactly the same partner that you had before you had your dear children (anymore than he should expect you to be exactly the same as you were bc - before children), but you very fairly should expect him to join you as a supportive double act, who will show his love for you by sharing the care of both of your DCs, and by showing that he still wants and needs to spend quality time with you, which now includes sharing time together with your lovely 2 children as well. That time could be the four of you all wrapped up warm and going to the park together, and then maybe having cuppas - and a hot chocolate for the 3 year old - in a nice café afterwards. If the weather is too bad to go out in, then having an impromptu picnic all together on the lounge floor can be fun, and when the weather gets warmer, and if you can afford it, visits altogether to places like a zoo, can be great fun too.
You sound very strong to me OP, and if you had only ever been a single mum you would have coped amazingly well! But you are not a single mum, you have a live in partner, the babies dad, so of course he should be both considering you, and communicating with you, and also sharing the mental load with you, as well as the physical one. Why só many of the PP's here today don't seem to understand that is very strange to me.
I hope you are fast asleep now OP, and that you can get a longer sleep without so many interruptions tonight xx
