<human>: Could you distill the essence of the text into 1-3 sentences?

Bf and I have been together 2 years. We live together. We both have exes of 5 years. He hadn't been dating his for 3 years before we met. I stopped dating mine a few months before we met. This was an issue at first but we resolved it. 

My bf has been bringing up both our exes whenever there is turmoil between us. He'll say something like "is this baggage from your ex or something? I'm just thinking so because my ex and I used to fight like this" Or he'll say "you're great with gifts, my ex always ruined my Christmas" etc. 

About 6 months ago my bf was going through therapy and felt the need to reach out to this ex and make amends. He showed me the message and it was alright, a little inappropriate, but for the most part fine. When I told him I thought certain things were inappropriate to say to her, he freaked out and said he would message her and say he didn't mean it that way or whatever I wanted. I told him it was fine. Then a few months after that I felt the need to reach out to my ex and make amends so I did, he read it, everything was fine, nothing weird. 

My question: Are we bringing up our exes too much? Is it normal to bring them up to show what faults were in the other relationship and all that?
<bot>: My bf keeps bringing up both our exes (always in a negative context) I'm just wondering how much is too much.
