Okay, if you are wondering it seems like the root causes of it are loneliness and I've never really felt like I've been truly accepted. Other than God.
NOW we're getting somewhere. See, we can't just treat the outer layer (finding a girlfriend) - that's a temporary solution. This will derail your thread though, for obvious reasons.
You know, the moment you truly realise how accepted and valued you are by God, other peoples' acceptance won't matter. And I know this sounds cliche but most of us here have been through that.
As for every other addiction, the root is our relationship with God, after all. If we work on that, like the branches that we are, getting help from the vine, we will bear fruits (and that's the freedom we all long for, the girlfriend you desire and MORE).
