How long have you two been together? What makes you think she would cheat on you? Is it something she said? Does she fancy this friend? Are they lunching everyday?
Based on what little info. you gave, I would say, you shouldn’t get worked up about this and make a big scene.
But it’s ok to be jealous occasionally, ’cause it reminds both people not to take each other for granted. Chat to her about it. 🙄
well if you trust her you should not be all 😕 but one thing have she been acting diffrent with you? have she ever told you or click on you when shes with him? have she ever cheated on you?
i think the best way is to let her go out and explore the options. If she will have true love for U, she will ultimately return to U… dont be possessive — its too early for all that…
