Yes, you definitely do. I'm so sorry to hear what is happening. There has been a big change of events in a very short time for you so it is understandable the pain you feel.
I wouldn't say "give up" per say, but maybe take a break. Start working on yourself right now. You are what matters to you. He shouldn't matter to you right now. So as much as it sounds like a broken record and believe me I know, as people are CONSTANTLY saying it to me, take this time to love yourself. You are a good person, you didn't CHOOSE to be in this situation, but you can CHOOSE how you are going to get through it. I know how you feel right now, as my own situation is slowing falling through the cracks as we speak. It sucks, it sucks so bad sometimes I want to crawl in a hole and go away forever. But I look down at my two little boys and realize I have my whole life ahead of me. We are going to be fine. It doesn't feel that way right now, but we will. Let him go, if its meant to be he WILL come back. Sorry again, take care of yourself.
