Best way to meet this need is to have a healthy, emotionally supportive relationship with yourself. Then you've always got someone to take care of you, someone who's got your back, someone to be proud of you, someone to comfort you.
When we grow up, we learn how to parent ourselves; then we don't need our parents any more, and can take care of our own needs. But our parents show us how to parent, and we replicate their patterns. Monkey see, monkey do. Your Mum's response ('well, all men are like that', 'what do you expect?') doesn't listen to, cater for, or respect your needs. It roundly dismisses them, and minimises them (basically by saying they're silly, because the negative result you got was so obviously going to happen), and so now, that's what you do to yourself. You dismiss and minimise your needs. That's how you've been taught to look after yourself, because that's how your parents looked after you.
It's why you put up with a relationship for so long that dismissed and minimised your needs. It's what you're used to.
Create a relationship with yourself that's loving and accepting. Once you do this, you won't feel 'alone' and lonely. You'll feel taken care of, because you are taking on the adult responsibility of looking after you, and all the bits of you inside that are wild and childlike and still feel rejected and unheard. That kid you used to be is still you, and it's your job to look after her, poor little thing that she is. Listen to her. Indulge her. Above all, respect her. She's your heart and soul, and when she's got over all the crap she's been through, with your support, she'll be the one to warn you when your boundaries are being crossed, and she'll support you.
