I would really appreciate some advice on my situation.

Nearly 2 years ago i started to date a guy in the uk, he was on student visa and had over stayed his stay, he had been here for a maximum of 5 years and without realising he had over stayed he was asked to leave so he had to go back to pakistan. Now being over a year, and due to family complications i cant marry him, however his father is a uk resident, but coz my bf is 29 years old his father cant bring him over and neither can i bring him over on marriage visa. Can someone tell me what would be our options please.

Thanks in advance.
