Big problem with boyfriend/husband and ready to make a decision.?

I have been with my bf for 5 yrs but, among the good things he has he has one bad habit I HATE! He loves cycling and has bought many things for this hobby. I can't seem to get thru him is that he is not helping me financially the way he should cuz he has truck pmt,credit card pmt,and ins, ans so on he helps me with what he can but the point is he is not mature what pist me off and is what i need help is that He spent 3000 dlls on a new bike and wasted all the money we had gotten on our incometax he got tires for his truck and wasted all the money. I did spend 3000 too but bought clothes for kids, paid bills and pd ahead 2 mths of rent which he says i wasted money to but i did for our benefit which we don't gain anything from the stupid bike. he bought this bike without my permission and gets mad cuz i am so pist off i will not speak to him. I have asked him to leave the house and wont go. also, I have given our relationship alot of thought and I feel i am not part of the family. Exp: He goes to mexico for vacation every year with his family and we never get invited (my Kids and me). his sister just posted pics of her family and She didn't put one singlr pic of me or my kids only her new sister in law and when i commented what a pretty family she said oh thanks your not here cuz i dont have any pics of you lol. WTF hello after 5 ys and no pics na that is bull crap. but my bf wont leave despite telling him he needs to leave his excuse is I will go to the garage and you will do what u want. I love him but I feel so confused I dont think i deserve this at all I work all day and he gets mad but i tell him i need to pay bills bills he has no commitment to paying. well he says he loves me but i feel it's just commodity is what he loves what should i do? I am at a cross roads with love and anger and so many feelings it is so hard to think clearly and have a view from a different point. I would like to say all I have gone thru but it is to much. I would like some good advise and not just some smart mouth advice trying to judge me rather than helping. Please help me see the true color of things.
