Outdoor faucet issues looking for advice

If I did this right you will see a photo of my garden hose. When I took it off in winter time the 2 top pieces are from the faucet. I tried everything wd40, lockjaw pliers I can't get them unfused. Here is the problem though I would like to use my faucet and attach a new hose and I am having trouble finding anything that would fit

Hopefully I have a photo of the faucet. I did buy a brass connector but it won't fit. Curious for any advice thanks
