They (my friend and her bf) got together in the first place because he cheated on his gf with her, while she knew full well he was already in a relationship...but that's a long story so I'll keep it moving.So she basically asked me if she's over-reacting by not being comfortable with the fact that her bf still texts his ex. I don't know what to say since there's not a whole lot of info to go off; I don't know how long they've been talking, what they talk about, etc. frankly I know it's not my business. I want to say she's feeling insecure b/c of the way she got in her relationship in the first place, so now she's paranoid that his feelings for the ex may come back (I mean they'd been together for 3 yrs, before he cheated, so...). But I honestly don't know. What are your thoughts? less
