I feel awful....

I'm a single mom not by choice SO of 6.5 yrs left us. I'm giving my baby a huge shower she's not gonna want for anything on the count of her stupid dad. My ex (before BD) and a few male friends of mine knew that BD and I had been having issues. Is it wrong that these guys have been chipping in (monetarily) to help me the shower. They are invited and they are honestly just friends but I feel kinda bad this isn't their kid and they are still helping out. Should I feel crappy. I'm not leading them on in anyway
