Deleting convos

Should I be bothered kasi may pinsan tong si jowa na gustong gusto nya lagi kausap. Pag may fb story si girl, magrereply sya ng heart and heart eyes emoji. I know pinsan nya yun and wala ako problema kay girl kasi lagi naman sya siniseen lang pero tong si jowa, lagi nya talaga chinachat, like he's insisting to start a conversation. Tapos everytime he would do that, afterwards binubura nya yung convo/replies nya with his pinsan's story. He doesnt know I have access sa fb nya. Im 7 months preggy at nasstress na ko.
