You are correct. Conway was not anti-Trump while Kellyanne was running Trump's campaign (this likely accounts for the donation). After the election, he was even offered a high position in President Trump's DOJ.
However, Conway didn't take the job, and there was no plausible explanation other than (as you said) he was jealous and couldn't handle Kellyanne's fame. Instead, he turned on a dime; helped start the Lincoln group; and achieved his own "fame" by continually attacking Trump.
Kellyanne said in recent interview that she considered his lack of support and public humiliation a complete betrayal of her, as well as their marriage vows.
