>>13447766Well I just reread OP's post and didn't realize she broke up with him before he texted her sister's boyfriend.
In that case, I revise my first answer. OP should tell her the truth.
After she broke up with him, he was motivated to improve himself, took tren and it fucked with his attitude (telling her to fuck off) and libido (messaged multiple girls a day plus the text to the sister's bf).
OP could sprinkle in how long the relationship was, how much he misses her (plus it even motivated him to change), and how sorry he is.
Actually, now that I think about it, he could still weave in the contrition.
>talk to sister's bf>sell a sob story>he feels bad for you>he forgives you>she finds out>she hates you lessI think it still helps.
