How do I live with out my SO?

It is hard. The only thing that really helps is time. You will slowly find yourself thinking about them less and less. One day you find that you didn’t think of them yesterday. That turns into weeks and then months.

It just takes time.

By knowing that you shouldn’t settle.

Find meaning and strength in being alone instead of relying on someone else to be a whole person yourself.

Everybody’s been there at some point. It’s very hard. Try to keep busy and connect with friends that have meaning to you. When you’re busy, it is harder to obsess about the pain and after a time as @johnpowell says, the pain begins to lessen.

When your love life ebbs, throw yourself into your work. It distracts you from the longing. Better yet, it makes you more attractive and interesting.

Breaking up is hard to do. Know that the sadness does pass. Call up some friends and try to occupy your mind.

I understand about the the fat girl. I am really sad.

You will get used to being without him. You will find your “new normal” and probably come to find you are, in fact, better off with out him.

Exercise a lot. Eat healthy foods. Give yourself time.

Also, I think sometimes it’s helpful to think of relationship loss through ending a relationship or death, as a really bad cold. Suppose you woke up one morning with a sore throat and a headache. You probably wouldn’t beat yourself up or get emotionally torn up by it. You’d wait, and wait until your nose stopped running and your head stopped hurting. Meanwhile maybe you’d watch television, read a book, chill out. Wait. Relationship losses hurt worse, and I’m not trying to suggest they’re as significant as a cold, but after a few days of grieving, I’ve found this helpful—to acknowledge that my body and mind need some time to repair themselves and to recover from the injury. It becomes less about you and the other person, and more about you and the healing.

I’ve heard “the best way to get over a person is to get under a new one”.

If playing Russian roulette with STDs don’t tickle your fancy, however, you might try adopting an animal. Having another creature love you and offer up its devotion makes us feel a whole lot better about ourselves, and can help to replace what your SO gave you.
