Wakuu I need y'all help, I've been seen this fine kmtc Chile since March 2023,all was well even invited her to my bros graduation after-party last year she got to meet my folks.Fast forward around May this year akaenda placement at a certain hospital in machakos ,made a new best girlfie akaanza kuitiwa form a lot ,like she'd call akiwa tipsy ananiambia wako dunda with some staff wa hio hosi alikuwa ameenda placement, there's even a day she told me they spending the night in a airBnB and let me tell you hapo ndo I started feeling like my heart was being ripped off my chest .Fast forward to last weekend tukameet KFC akiwa na her bestie and she asked me to drive them home, nikadrop off the friend kwanza then proceeded to her place . Guy's I was shocked kupata amefurnish her room, I'm talking a tapestry,water dispensers, she has a couple pairs of new ones and Jordans noticed cos I gifted her the shoe rack a while back,a stereo,a cooker .like I'm one one sure her dad didn't buy her all these things considering anafaa kumaliza shule next year. She's gone from living in a comrades room to a fully furnished self contained house.This woke up my spider senses again and I began feeling like there's a brother in law doing all that. Mniambie ukweli hapa nangogewa na si mayai sio ? Sai nimecut off communication,she called five times Jana didn't pick up I don't know how to break it down to her .. what should I do ,pretend till she fucks up or make conclusions in my head and just forget I ever met her?
