Is it normal that my boyfriend never pays?

I have recently finished a degree at uni and have a part time job. I am desperately looking for full time work at the moment but luckily my part time job has given me lots of overtime to help tide me over financially whilst seeking full time employment. My boyfriend has had a full time job which pays well since we've been together. I've worked out that he earns roughly about three times what I earn.

I pay for almost everything we do. I can actually count on one hand the amount of times he's paid for a meal/coffee etc whereas I know that I have spent hundreds of pounds on going for meals,cinema,drinks etc.
Whilst being a full time student , when I received my loan I treated us to lots of meals/nights out etc , I also treated him to a £40 t-shirt but I quickly realized that my student loan was less that one months wages for him and felt foolish because he had never done the same sort of thing for me.
I've also recently noticed lately that when we go out , he almost always forgets his card or never has cash on him. I feel that this is because he has become so complacent with me paying for things it is just expected. I am starting to feel taken advantage of.

We recently attended one of my uni friends wedding party. I planned to buy myself a new dress to wear to look nice as I hadnt seen my uni friends for a while. Unfortunately , due trips to the pub , coffee and Sainsburys which I ended up paying for , I couldnt afford a new dress and had to wear one that I already had. He bought himself some new clothes to wear and said to me for a joke that he was going to 'out do' me at the party. When I got dressed he questioned me about why I hadnt bought a new dress. This really upset me as it made me realise that he's happy to sit back and let me spend all my money on nights out and keeps all of his money to spend on himself. He's always buying himself new clothes , shoes , guitar accessories , whereas Im left with nothing spare for myself at the end of the month and have to go without.

Whilst at the party my friends were telling me about how much their boyfriends spoiled them with jewellery and meals etc. I felt too embarrassed to say that not only has my boyfriend NEVER bought me anything but he's happy to sit back and let me spend all my money on days/nights out and see me go without while he's got all his money for himself.

We've talked about this numerous times , even my mother has questioned him about why all my money is gone and that he never pays for anything. He always replies ' you must let me pay for things' or ' I will next time' but next time comes around and he never does. He's been saying for a long time that he would like to live with me but has made no attempt to save any money from his salary towards moving in together. Now I have a full time job , he's telling me not to 'go mad' with my first pay cheque as we need to save to move in together even though all of his pay cheques have gone on clothes.
