So my bestie is my made of honor but ive noticed in the last month its been a change in her we went from talking everyday to im luck if here from her unless I reach...that a even iffy put i end up have to change my wedding date push it back to month my guest list has always been 26 ppl she knew this from the beginning that it was a cruise wedding cuz im litterly pay for everything so money isnt the issue so I asked her if she would still be able to come and her reply was "yes but I ain't tryna stress tf outta her son being around a shitload of strangers and loudness with no way home especially" like you knew from the jump start that was going to be a big possibility so I bit my tongue was like okay.... I get left it at that thought ill give few day so texting her yesterday like hey are we okay? Are u okay ? And she read nothing like how do fix something or no if something needs fixing if she isnt communicate im so heartbroken she been through my side by the worst things in my life my friends and family already small just feel since this wedding it changed or friendship...ive litterly been engaged only 3 months
