I don't think anyone should "chose to give up." However, the old script that you have to be married or in a relationship to be content with your life needs to die already. People who seem to be arguing with their significant other half the time ask me when I'm going to get married and it just feels silly. It's more like, "when are you going to get a divorce," to be honest.
A friend of mine has this mentality where he has to be in a relationship and he's always looking forward to marriage. He's depressed when it doesn't work out, he's morose when he's alone, but then when he's in a relationship, he seems to cycle constantly between euphoria and emotional exhaustion. With so many people bound to unhappy relationships, it's easy to see why rushing into commitments isn't necessarily a good life choice.
If it happens, then it happens. If it doesn't, then it doesn't. Either way should be fine. I think it's best to keep an open mind.
