dilema, can any1 help?

I'll start with giving u my brothers and sisters Salaam, i hope u are all in the best of health. I am a new memeber and i really, really need some advice.

I'll briefly tel u my story,i went pakistan a last year and as they do, they asked for my hand in marriage for my cousin,who is not my type at all and i would never get married in Pakistan because there not on my level, most are more cultural then religous.
mum really wanted me too, and when i got back to England my aunty who's son they wanted me to get married went and told the whole family,that i got engaged to her son before i came back to England,which wasnt true.
so the whole family thinks we are engaged which isnt true so i stopped talking to family in pakistan because it really hurt me.
mum still wants me to go back home but it isnt happening.

anyway iv come across a muslim who has reverted to islam mashallah and has been a Muslim for over 3years and is practicing. we get on really, really well even support the same football team. he has asked me to marry him, i want too but i know family are going to have a problem with it.
i dont care about extended family just imediate.
sister and cousin know about him and are being supportive but i know my brothers and mum will not accept it and will end up dis-owning me. they will think i don't want to get married to cousin because i was sneaking around with a white boy, they are very cultural. my dad might support me 50/50 chance.

i've tried finding a Pakistani to marry but i don't connect with them and it doesnt feel the same.

what shall i do, please help with advice?
