Help. Married lover forgot my birthday and handed me a wad of cash?

I'm a 22yr old woman. I'm seeing a 42yr old gorgous totally loaded man whos married. His wife dont understand him and they dont sleep 2gether anymore. Hes only staying another while until his kid does her exams this summer. Then hes showed me pics of a penthouse we are going to have as our family home. It wont be easy and i know itl take time for him, but i know hes crazy for me and i'm willing to wait. I'm available 24/7 for him, when he calls i drop all and go. I'm spoiled rotten. A few times per week he rents a room in a real posh hotel in the city centre, i go up to the room, we do it repeatedly and then if he has to go i have the room for the whole night and can bring my girlfriends round and use it. Some guys choose 3 star hotels with no spas. He throws in spa treatments for me and my friend. How cool is this? I've a nice figure, i'm slim but i've huge , they are 30F, but i'd like to be even bigger. He loves big s. He says hel pay for me to get them bigger, imagine...the whole lot. Friends have to save for ages, hes choosing an exclusive clinic. He buys me thrashy lingerie and cannot keep his hands off me. Howver, it was my birthday yesterday and he forgot. I 'm upset, he just handed me a wad of cash, no thought put into it. Also my friends is beginning to flirt and hes invited her to a hotel wtih me tommorow evening for tea and drinks...wtf is she coming for/
