If you got out of a relationship and you continue to fail in your relationships but see your past romantic partners in successful relationships maybe it's time to look at yourself and reevaluate what you're seeking in a mate and whether or not your expectations are realistic. Do you want a partner who buys you nice things? Do you get angry when they don't? Stop. It's totally fine for you to want gifts. There's nothing wrong with a person who finds it's romantic when their partner thinks of them and wants their face to light up. But why are you angry? Did you talk about it? Did your partner know you were expecting a gift? What are you really asking when you're asking your partner to fulfill your needs. Are you wanting them to think of you when you're not around? Or do you want them to read your mind? Check your expectations and make sure they're realistic before you stir the pot.
