He (28M) wants to pay (15K) for me (26F) to get a breast augmentation. Is it rude for me to take the money?

He’s my boyfriend of a year, and I (26F) don’t think he (28M) should expect anything in return for him giving me money to get a breast augmentation, which I’ve considered for years anyway. He (28M) doesn’t like my small breasts but would like a girlfriend with bigger breasts. I (26F) had no idea he (28M) felt this way until he (28M) brought it up in an argument. Most of my life, I (26F) have considered myself very insecure about my chest size. I (26F) have since researched surgeons and made appointments with them and scheduled an appointment with my primary care to get pre-approval for the procedure. He (28M) said that he (28M) will pay for the procedure but doesn’t want me (26F) to go through with it if we (M&F) were to break up. He (28M) said it’s not fair that he (28M) pays for it and then we (M&F) break up, and that he (28M) will find himself in a situation where he (28M) has paid for the breasts of another woman that he (28M) doesn’t even date anymore. He (28M) said that if he (28M) pays for my (26F) breasts then he (28M) wants to enjoy them for the rest of his (28M) life. So I (26F) should be willing to be in a relationship with him (28M) for the rest of my (26F) life. He (28M) wants me (26F) to sign a contact saying that I (26F) will stay with him (28M) for the rest of my (26F) life if he (28M) pays for my (26F) breast implants. He (28M) said that if I (26F) am truly serious about getting implants then I (26F) wouldn’t care about signing a contact stating that I (26F) will stay with him (28M) for the rest of my (26F) life, as I (26F) am so desperate to have breasts. I (26F) feel like, hell, I (26F) am already here. I’ve (26F) already been with him (28M) for 1 year, and I (26F) am committed to him (28M) 100%. He (28M) is everything I (26F) ever dreamed of. And it’s not like a contract is binding anyway, so what’s (28M) the difference? He (28M) will have paid for my (26F) breasts, which I (26F) really want, and I (26F) get to stay with the love of my (26F) life. <br><br>Should I (26F) be offended that he (28M) wants me (26F) to sign a stupid contract? He (28M) won’t give me (26F) the money for the implants unless I (26F) sign the contract.<br><br>Can someone please help me (26F) with this? Is it rude of him (28M) to expect me (26F) to stay with him (28M) for the rest of my (26F) life if he (28M) pays for my (26F) breasts? Is there anything wrong with signing a contract stating that I (26F) will stay with him (28M) for the rest of my (26F) life?<br><br>&#x200B;
