Need some of thoughts

I had been thinking alot of times, which i wanted to had breakup with my bf. I dunnno the love had go down on the slope and i no more loving him, this few weeks he had been late coming back home, and like to go out without me. I did not ask him to bring me go, but when the time to stay at home, he wants to go out and rather to stay at home> Do i over sensitive? which i had been asking question by myself?
Are he is the one who care take care of my rest of my life? i dislike him, which when he go malaysia over the weekend, and spend all the money, likes to ask me for money.. this is really i thru. I also dunno what to do with this relationship. I quite hopeless right now. I hope someone who can lighten up my mind...
