Maybe It’s Me...

My bf told me he called out from work for Tuesday so we can spend the day together. Today, he tells me outta no where, “I called out of work on Tuesday to spend time with my cousin, she’s like my sister, but come over in the morning before she gets here.” I feel kinda lied to and also like he doesn’t want me to hang out with him & his cousin. Maybe it’s me, I’m literally a day off my period and probably super hormonal still? What do you gals say?
