Tired of trying

Don't know what to do. We have been together for 3 years and have 14 month old how is amazing. Sometimes I think its just me being selfish but I have needs, am human and we all only have one life. When I ask for just about anything there is so much resistance. I furnish the new car pay all her bills so she can stay at home with the our child. Wants to get hair done, go out for drinks with girls, ext. Here's the money. But if I want morning sex No with an attitude. I still waiting for the valetines present of her in something sexy. I'm.just making story short the issues are everyday things constantly. Don't know how long I can take this but do not want to break up the family.
