Nobody is saying she can't have standards when it comes to dating. But you can't assume every guy who comes up to you is doing so because he wants to motorboat you lmfao.
And yeah, it wouldn't hurt for her to go see a therapist to get over that state of mind. She can want a guy who buys her flowers, takes her on thoughtfully curated dates, professes love in the rain like a Nicholas Sparks book etc. Her tits are a part of her body so he's going to occasionally even in public sneak a glance lmfao.
When my ex and I first met as friends I had no idea about her huge tits, even from her IG or random snaps bc she never flaunted them the way Isabella does. It literally wasn't until we started getting closer and she took her clothes off in front of me that I saw she had DD's.
Not saying she dug this hole for herself, but she doesn't have to wear revealing or tight cuts every single day. Then she could go out, relax, have a drink and let a guy approach her and see if the convo is engaging and go from there.
