Option 5:
Stop comparing yourself to your sister. Men of virtue do not show up and say to your father “show me your daughters” and then they pick the one they see as prettiest, at least not in the modern Western world.
You run the risk for ending up in a destructive relationship because you have told yourself “I’d better take anything I can get!!”
Get out in the community, get involved at the Diocese level with Catholic groups and events. Make FRIENDS. The marriages that last, every one of them, will tell you that they married their best friend.
I know what I am talking about. I have a physical deformity that cannot be hidden with cosmetics, corrected with surgery, 50 years ago I would have been in a sideshow at a circus. Many of the people with my deformity end up in terrible exploitative relationships because they feel they have to take anything that is offered.
One thing I learned is to always put my best foot forward. My hair is kept in a current style, well groomed. My brows are shaped, I take care of my skin and my teeth, I wear cosmetics to enhance my face (you can learn this from YouTube and it is not expensive). Clothes are in good shape, better to have a capsule wardrobe of 10 items that fit well instead of a closet of cheap stuff that looks like a mess. Nails are trimmed and filed.
I watch my posture, my handbag and my shoes are in good repair and as stylish as I can be (again, one pair of high quality shoes is better than a closet of Payless junk). I have practiced everything from how I look when I eat to my handshake.
Keep your mind sharp, read real books, be intellectually active.
Have a list of non-negotiables and stick with them. Do NOT settle.
