Firstly thank you for reverting back. With your second answer, it became more clear that from where your doubts might be stemming. The doubts that you are having are very natural, anybody in your place might be thinking the same. Have you tried conveying exactly what you shared here, to your boyfriend- i.e. why isn't he asking money from his parents and why he has not carefully handled your hard-earned money?
As I am hearing from you, and a lot of details about your relational dynamics couldn't be shared completely here, therefore it is difficult to say something about your boyfriend's perspective. One good thing you have done, by putting a boundary- " I made it very clear not to ask for money." I feel, now you need to be assertive as well, when you try to convey to him that you need his contribution somewhere and you want him too, to take some responsibilities.
And I also feel that your concern needs to be addressed and explored in-depth to provide you appropriate support. Therefore, I encourage you to connect with an Expert for sessions on this platform.
