I don't even know why I am writing this but I am just hoping hearing some other people's opinions or experience will help me realise what is the best option to do 
me and my OH had our little girl 15 months ago and haven't really been right ever since... we constantly bicker and Get angry with eachother over things that shouldn't even matter, I'm scared this is now going on in front of our little one and she is picking up on all the negativity between us both so Iv said I want to leave and both go separate ways to be happy and give her the happiness she deserves, not a stressed unhappy miserable home what we are living in most days now.
We have been together 7 years, we have had many ups and downs like normal couples do but have always been like best friends which I can't work out if that's a good or bad thing sometimes as we laugh so hard together and really understand eachother, he gets me like nobody else really has but yet we don't have the best sex life and rarely want to show eachother affection 
I work from home as a florist so my daily routine is quite tough on me which I think I am causing a few more arguments through stress... I am a full time mum all day then when my little one goes to bed I work all night while probably 10-11pm and go to bed, I don't feel like I have a life through the week but I don't have a choice but to do this!
Another major thing is I really do not get along with his parents anymore and we seem to argue about his family so much because I feel he is scared of them and doesn't speak up when he should. There is lots that have gone on which I don't need to get into but I don't feel comfortable around them anymore I don't like there company and I'm really struggling to carry on pretending to be happy for my daughter and OHs sake :-(
we are now on the verge of selling the house and moving on for good and the thought of it really is scaring me to death... our little girl not having us together, not making family memories together etc is thrashing my head and I cannot think what really is for the best. My OH hasn't took this well, even though last week he was agreeing saying it needs to end and we are toxic towards eachother. He is now constantly being horrible to me saying shitty things like he will resent me forever for splitting this family up, it's breaking my heart but deep down I know he isn't meaning he is just upset and hurt that it has come to this. I am considering suggesting counselling as a last resort at giving things one last shot but I'm scared it's past that point and we are just wasting time being so unhappy together and miserable everyday.
I will now stop rambling but just hope someone can shed any light or has been in a similar position who can actually understand me and know how this feels :-( Has anyone else tried counselling as a last resort or got through a really rough patch like this? Or is this really the end and I am holding on to that tiny bit of false hope
