Help! My boyfriend won't stop talking about some girl named Parlay.

ANY GIVEN SUNDAY-  I think my boyfriend is cheating on me…Again! He won't stop conspiring with his friends on the phone and then whispering about someone named Parlay. I'm starting to get suspicious. 

It keeps happening every Monday night, every Thursday night, and literally all day on Sunday. He even skipped Church last week because he said he had to "figure out his Parlay." Seriously, who is this b*tch and who does she think she is, trying to steal my man? 

Never mind the fact that he already committed a sin for her by skipping Mass. The only sin he's ever committed for me was helping hide my cigarettes, that he bought, from my mom when she came to visit. 

Yesterday was my last straw. We were sitting down watching the Eagles game when he jumped up and screamed "My parlay just hit!" and started running around his apartment. He immediately went into his bedroom and I could hear him on the phone yelling passionately about this "Parlay." 

"That's it!" I put my foot down and demanded to see his phone. 

"Babe, I promise I'm not hiding anything" he whispered sheepishly, handing it over. 

I began scrolling through it, but he must've deleted everything. The only messages I could find about a "Parlay" were from DraftKings. I guess he's into girls who play sports?
