Yesterday, I met my ex in a store k!ssing her new boyfriend in front of me, I was watching them, she saw me then she k!ssed him more and asked me what I was doing there?

I told her my wife is pregnant and I am there to buy baby stuffs and I am very very happy. I spoke as if she asked how i was feeling I proceeded in the store as she was looking at me, I bought 3 buckets, diapers, a baby seat and a baby bed with sponge with soaps, baby trawler, bicycle baby wears then I called an uber and left, She and her boyfriend were looking at me and I felt good.

The issue now is if you know any woman who has given birth, I am selling buckets, diapers, baby seats, soaps and sponges at affordable prices. can’t take them back to the store because I lost the the receipt.
Please help your own brother, l was supposed to go and pay our electricity and water bill with the money.
