So my mom claims she has pictures of my ex with another woman and evidence of him with other women while I was pregnant but every time I ask her to see it she says no, she doesn't wanna hurt my feelings but why say some shit like that if you won't show me? I think she's lying and is just happy about my breakup (she didn't like my ex because he didn't have any money) does that sound like she's lying to you guys? She claims to have all this evidence and know all this dirt on him but won't show me anything
