need some advice

well let's cut a long story short. Iv been with my husband for 11 years and been married for 3, we have 2 children together 4&5 . he works self employed I stay home and look after the children and house. yes he is old fashioned.

well anyway it's like he don't have no time for me he has become a pig. he comes home from work lays on sofa and don't move even at weekends. he never wants to do anything with the children he never seems untreated in us all he wanna do is concentrate on him self. he happy buying him self stuff all the time and it's what he wants when he wants. never asks if the kids are sorted or anything they need or me. when I tell him he can't have new sound system for his car as I need to buy school shoes. he kicks off n it's all my fault. Yeah he works and I respect that but I'm a mother of 2 young children I don't drive so all year round I walk and do everything he dosnt he won't even go shopping I do it and carry it home. I do feel he only want me for sex and to sort the kids. I really don't no my head says walk away and start again but another part is screaming I love him but also hating him at the same time
