I want to introduce a female rabbit to my male rabbit what is the best way?

i have a 7 month old castrated male rabbit and today i saw a really cute 7 weeks old female rabbit and i thought that maybe she would make a nice playmate for my bun so he wouldnt get lonely when i go on vacation.. im planning on buying a bigger cage and then introducing them.. would it be possible for them to get along? how is the best way to introduce them? would my male get jealous if i pet her seeing as hes a bit clingy?
