Hi i just want someone to talk to about all of this......and also others opinions of the situation i am in.

I have been with my BF for almost 4 years now and we have had custody of his 2 boys for 2 years they are now 4 and 8 years old. They still see their mum a couple of times a week but it is strained as she neglects them severely but they think the sun shines out of her backside.
ok so 2 years ago i moved from the mainland to this stupid little island where i have no family or friends,i gave up the job i loved and a social life to help him and provide some stability for the boys.
I am now the primary care giver, i found a job similar to the one i had on the mainland but i am the one who has to do school hours to fit around the kids!even though i am only step mum.I have to sort out all the school stuff/dates to remember etc.
So daily routine is get up, sort kids out, sort me out, get to school, rush to work....work(30 hours over 5 days a week)....rush back get kids from school, go home, get housework done/clothes ready for next day,sandwiches/lunchboxes for next day etc, BF gets home around 5 then goes off to do an hour and a half weight lifting/fitness training (5 days a week!!) while i get dinner ready so we dont all eat until he gets back at around 6.30pm then 4 year old bed at 7.30,8 yr old at 8.30.
After dinner BF will then either go on the computer or do extra sit-ups or pushups or play playstation. I get to sit down comfily at around 8pm once the little one is in bed,once my ankles are so swollen i cant take anymore.
I have asked him to cut down on his training and have blatantly told him i cannot cope with it all but he just says he is not cutting down his training and thats that,i get the feeling i just have to lump it,although he does say leave it all until he gets back and he will do it all........what??so we all eat at 8pm!! i like to get things done early so we can all relax.
Anyway thats just part of it.....it gets to the point i have to pick up after him as he doesnt even seen to know how to tidy up after himself or do the basics. like he will drip a t bag accross the floor to the bin and not even notice just after i have mopped the floor etc.
I have good standards in the home as far as being clean and hygiene go but not obsessive and im trying to teach the boys these too, like if they pee on the loo they wipe it up and they always wash their hands after toilet and before eating etc but its hard trying to instill this into them when its just me doing it,the boys are also very boisterous and i dont get any help in trying to calm them down.he play fights with them and makes it worse.
Im scared that when the baby comes this will get worse as i will be at home everyday so he will think it is "my duty" to do everything.i also worry that the baby will get hurt accidentally by the boys.
Dont get me wrong he is a nice bloke and i love him but he is just thoughtless and seems to think this is what i moved in with him for!!
As for trying to talk to him. I always try to make time with him each day to talk,spend time together but he always gets distracted by the tv so ill be talking and he wont have a clue what i have said. I have a moan at him for this but then he just accuses me of nagging etc.
IS IT ME?????

Also when it comes to buying stuff it is all down to me what to get or think about what we need/he has no interest. The other day in a shop just him and me i said to him to come and have a look at the baby clothes with me and he just walked off and said he was going to find some clothes for the boys instead. This baby only has a few things so far and even then they are only very basic so its not like im obsessed.
I have been thinking recently if it would be better on my own?
I also feel very sad that this is my first baby and it wont have a nursery,most things i have been trying to get cheap on ebay etc and also i wont get that first baby experience,like not having to get dressed in the morning if i dont want to and being able to relax a bit for myself as i know i will still be doing school runs and running about after these 3 as well as the baby.
Im really scared about the birth stuff and i read what people on here say about their partners being really supportive and stuff throughout their pregnancies and it makes me sad that mine isnt like that. Im also worrying that when in labour he will just be watching tv somewhere and not giving me the support i need.
What can i do? what would everyone else do?
Sorry if this is very personal,i have no one else local to talk to about this.
