Sandy
Sandy is Spongebob's friend, not his 'girlfriend'.
Sandy Linter was Gia Carangi's love/girlfriend.
It is mentioned first that the choice was to marry or move to Florida, which means that Sandy is pregnant. This is easily overlooked because of Sodapop's personality. Then, near the end, it was mentioned that it wasn't his, which means that the baby inside Sandy was not Soda's, and that she betrayed him. Even so, he still wanted to marry her, but was rejected.
