F and M have been dating for 3/4 months and everything is going well. Theres been a couple times where she's had to give him a push in planning things to do together outside (eg going on dates instead of chilling inside.) He has been improving and wanting to make her happy. They're open communicators, and theres been no signs of cheating - she knows all his friends etc. However, she saw an unknown name on his best friends list on snap chat when sending something to herself so she asked him about it, and he admitted it was someone he had a situationship before. She questioned why they're still talking, and he said its only streak and that They dont actually talk.
Is this normal? Do people still stay in touch with exs or people they slept with? Theyve never checked each others phones. So she feels like he's hiding something from her. Is it worth the breakup?
