Should I break no contact / try to be friends…

PLS give advice . Me and ex broke up a little less than 7 months ago now. I want to be friends or at least cordial… we haven’t talked since the day we broke up aside from a card we mailed to each other saying like take care I love you forever whatever corny lesbian stuff. It was a mutual(?) break up over us being long distance and unsure how to close the distance (obligations preventing whatever etc).

Is it a bad idea to text her? to ask to call? It feels weird we said let’s be friends but neither of us and followed up on it. I meant it. But maybe I’m delusional and lesbian. Maybe I should let sleeping dogs lie. I love her. It isn’t based in wanting to get back together, but to not feel like abolute strangers anymore…

Has anyone ever tried to be friends with an ex? After letting some true time pass and reaching back out? Is it worth? Dumb? Helppppplllll
