Help me fly my boyfriend to Cali

Me and my boyfriend live almost opposite sides of the world with me in california and him England. I had an amazing opportunity to go out and see him for 10 days which is all we could really afford and unfortunately it took up most if not all our money and savings which makes it hard for him to come and see me.

We are trying to be with each other again and would greatly appreciate anything you give to help him come and visit me.
I am planning on going to university in England to be with him and further us and my career but money is really tight. Normally we would try and figure it out but it's hard being away from him and I'd love to be able to see my boyfriend even for a short amount of time.
