In a relationship with my aunt, wanted some helo regarding it

So i am 20m and my bua is 46F and we both are punjabi btw. I have been with my bua for around 4 months now. It is going great with her, we have sex around 2-3 times a month. We have become really close to each other in terms of ”LOVE” , to like such a way that she is becoming really possessive towards me. Like she doesn’t want that i should talk to other guys or anything. Its becoming more like wife behaviour then gf. Although she guys be things also like games, and just a month back bought me a real madrid t shirt ( which was like 5k) so its also like a sugar mommy for me lol
