I think my husband is having an affair, what are the signs?

So we’re been married 15 years and have 3 children. It hasn’t been the best relationship and the beginning years I wonder why I ever stuck around. Neither of us have ever cheated ( that I know of) but he has continuously over the years been caught talking to various woman in a sexual manner. He was never really affectionate and I remember the days he would have touch me if he wanted sex, or say he loved me when he did something wrong. Putting all that aside I went away in 2021 for a hen weekend, I met a male as you do, and nothing happened atall but for some reason I liked him, and I accepted his request on social media. By husband caught on a few weeks after I was back ( no conversations happened with this man past the weekend we were away) but a few photos likes etc. My husband since then has been what I can only call as obsessed with me. He constantly is hugging kissing, saying beautiful things, how much he loves me. This hasn’t wore off since. But I’m thinking now that maybe it’s not related to what happened with me and he’s having an affair. He’s very secretive of his phone, if I come in he will click off what he was on or quickly face it down. I found an ever too spray in his car (which hasn’t ever been used it’s me, nor do we use this and never has he mentioned this) along with various other situations such as him so say being out with his brother but me finding out from his brothers wife that the brother wasn’t out atall that night, he doesn’t answer the phone when out etc etc. So my question is, usually if you search affair info online it says the wife and spouse get further apart and he becomes distant, which isn’t happening here. He wants sex with me daily, we have a happy life and relationship… would an affair cause him to guiltily fall in love with me?
