Am I overreacting?

So I’m talking to this guy we both have feelings for eachother anyways, he had a toxic ex and everytime we get intimate he said he can’t because his ex ruined that for him. Now she’s claiming that he got her pregnant which she has lied before but I’m getting real tired of this whole entire thing 😫 I’m trying and telling him I’m different then his ex ... what would you guys do???? I told him to file a report she has called him 100 times a day no joke .
