I have been seeing (within covid rules) a man in his mid 30s since dec 2019. He is divorced, his EW left him for someone else.
I didn't really have any alarm bells until recently when he started to open up a little bit more about his past relationships. When we first started dating he had told me he was recently divorced and had been married to his ex for 4 years and together for 5. Then recently he mentioned getting married at 21 to her. So it's more like 15 years of marriage. He then tried to brazen it out with a "I've always told you that" line. He then changed tack to "wow, I always thought I had said that."
So, he obviously lied to me at the start. Maybe he thought I wouldn't be interested in someone who'd only had one partner for so long? He won't admit to the lie which is probably what upsets me the most. Is this a big deal, a red flag?
