Calm Before The Storm

Warning: Expect typos due to current mood and IPhone usage!

After a tense few days of bad weather brewing, I'm awaiting the storm to hopefully clear the air.
I have issues with arguing at the moment for several reasons, one being my mental and emotional state, which isn't strong or healthy, due to the impending birth and two being the promise I made to myself around the time of the wedding to not row.

By dividing up the current problems I could maybe decide if they are worthy of heated debate.

Kids, sex, pets, housemess, OHs general attitude towards me.

I haven't until now been able to fault The Boy's acceptance of the children. For him, without much discussion, he moved in with us. There was no action plan on how everyone would get along, it just all seemed to flow along naturally. The last few weeks have been difficult and I have noticed changes in everybody.

I guess I'm concerned that the boy is feeling resentful towards the kids. I'm not sure if it is money related or if it is to do with the house, but there is a definite weirdness. The only interaction him seems to have with them is to have a go at them in a monotone patronising fashion. Of course there will be times when he tells them off etc but it shouldn't be the only time he speaks to them. I worry and suspect the kids are not happy when he is lecturing them about mess as they gaze around the room and can see his.
Also, I loved that that we were all a family and don't want OH to just a nag and the kids to get fed up of him. There has to be a balance.

To follow on, the baby arrives soon and normally it causes the other kids to be anxious about being left out. I accept, well I hope that OH will be loving with the baby but worry how the others will feel about it.

Sex, I'm not sure what more to add that hasn't been covered in previous posts. But I'm sure the situation is about to get worse after having the baby.
My confidence is now rock bottom and I'm frightened that between us, it's now unrecoverable.
How do I explain to my OH that our last sexual attempt made me so devastated that for a split second I thought about leaving. We struggle to talk about stuff in general, sex is even more difficult as his defences are up. The thing that pisses me off most is that from the beginning, I have been open and told him what I like and need and he did the same. I have willingly participated in his things despite them being erm, new to me (that's the best way to describe it) and even though they are his "thing," I love being involved. Or I did. He doesn't even do that anymore. He has never really attempted to do any of mine. Maybe a little at first but not now.
It's not even a case of lack of skills. Sometimes you know sex will always be hopeless but i actually thought that I had found a kinky, pervy little soulmate in him, but he simply can't be arsed with having sex with me. This surely has to be my fault.

I can't even be bothered at this late hour to discuss the other topics other than to share my dilema of the dog.

About an hour ago, I was told that Arnie has to go. Guess I have to start the rehoming process tomorrow. I'm such an all round failure at present
