Serious gf , 6 months in. We see eye to eye on everything and want the same future. I’ve read her diary and been through her phone. Nothing sketchy whatsoever. She writes about me and our future .

Yesterday she gets a haircut and posts some selfies on her Snapchat story. I knew she’d get some messages about it and wanted to see how she’d handle them. I visit her in the middle of the day which isn’t usual for us. We met up at her grandmas place. I usually come over in the evening or we’ll just go out .

I look at her phone and she has a convo going with this guy . He said I’ve had a boner since 9 am I need your help.

She said “babe that wouldn’t be good for either of us”

The problem here is she called him babe , and she didn’t immediately block him.

On the car ride back home she must have hid the chat and set the messages to auto delete instead of save for 24 hours . She saw me holding her phone but wasn’t suspicious I was actually in it .

We’ve talked about living together and everything . She has a son who I love and loves me . He’s 3. She makes me cute little gifts. She loves me. She looks at me with genuine love. She can’t look at me without blushing. I give her the best sex of her life. We’re in love. Totally. So I’m super fucking confused .

How can I bring this up without looking weak, insecure , or beta. Do I just end it? What do I do?
