He doesn't want to marry someone who has a child but the child is not mine

[Naijablog]

ADVISE NEEDED.
My name is **********I live in Lagos. My sister got pregnant for someone and during delivery she died, Till date I don't know who was responsible for the pregnancy.

The girl is now 8 years now and I have been doing my best in caring for her. Since my sister's death no one has come for this.
i am not tired of caring for her, because God has blessed me with a lucrative business.She is in one of the best Primary School here in Lagos.
My problem now is that I met a guy early this year and told him everything about myself and my late sister, He said if he's to marry me he won't be able to accommodate the child, That he doesn't want to marry someone who has a child, Blessing is just like my own child.

First he complained that I buy expensive clothes for a child of 8 years that it's inappropriate, so I stopped. He then said I should register her in a government school instead of private school as the school is quite expensive, I told him I will think about it after this term.He got angry and said I want to be stubborn.My boyfriend is a nice guy and we hope to settle down together early next year,but my problem is my niece.

I discussed with her head teacher about giving her up for adoption she wasn't pleased about the idea but promised to look for someone who could just take the girl as a maid. I am not comfortable about giving her as a maid but for people to adopt her and care for her, She can come and visit me any time. Age is no longer on my side, I will be 37 by January 2022. No one has the right to judge me on this,I can't waste my whole life to please anybody. Blessing is a good girl, she won't give anyone headache.I have tried to reason with my guy but he still stick to his decision.I don't want to loose him,it wasn't easy having someone serious as it always last for a 2 or 3 months.I believe he is the right man for me, His family loves me and it's a signal that our Union will be blessed.
Before anyone will judge me, I love my niece and will always do.
