Think my gf [F20] is lying to me [M23]

Hello people of Reddit,

I am in a situation that I very much not like to be in but I need advice.

Been dating this girl for about 3 months and it’s been going good. We don’t spend much time together throughout the week (2-3 times) but only for a few hours of a time.

However, the other day is making me question her intentions on being in a relationship. 2 days ago I noticed on her instagram she had “archived” the only picture of us from Halloween. Aka, not visible on her instagram page. Also her Snapchat was in her bio but this has been up for a bit.

I texted her about this on why she removed it. She claimed that she had unfollowed some people and wanted to update her feed, and removed the only picture of us, while keeping her Snapchat in her bio. Another reason she claims is that her own mother had commented in-person that she looks fat in the picture, and was self conscious about it.

She also mentioned stuff such as me being all fit and in shape she felt fat next to me. This didn’t make a difference to me and she put the post back up. Then asked me to put pictures of us on my socials (even though I don’t post) cause she’s worried single girls will hit me up.

I need help.

TLDR: Gf removed only picture of us on insta, I texted her about it and claims the reason is her mother calling her fat.
