Toxic relationship I don't know?

My ex and I had broken up for 3 months.
During that 3 months we both did our thing
with other people. I found out that he was with
another girl and I got Petty and decided to
send him a video of me giving my new man
head. He did the same back yikes i know... (he
sent me a video of his new girl giving him
head) after that happened we cut off
communication for a while. Then couple
months later he ending hitting me up telling me
that. He misses me and wants to get back
together and how he can't love the other
women. So we decided to put everything aside
and get back together since we both were hurt
and being petty at the moment. What does that
say about him? What does that say about our
relationship? we ended up getting back
together I need y'all thoughts and opinions.
