I realize this might be a bit late but you can expect a small bird like a finch to live perhaps 5 to 7 years (although there are certainly cases of finches living longer).
When your female passes away, you can provide another finch as a companion to your male. This does not need to be a hen; many folks will keep a couple of gouldian males for their beautiful color. Gouldians tend not to be aggressive birds. I used to raise them (at one time had about 200 goulds) and it was very rare to see an aggressive one.
