Do I give him a second chance?

My bf and I (26&24) broke up a couple weeks ago. He started a new job in a new city about 3 hours away from me. Before the move, we were so happy and very in love and he was so assuring that nothing would change because he loves me so much. So he moved and a couple weeks later, I knew he was incredibly stressed and this job was taking a toll on him. He sat me down and explained that mentally, he is not in a good place and he cannot be the boyfriend I deserve and need at the moment. He is actively searching for a therapist covered by his insurance and we have been in contact several times and he repeatedly tells me that he is still so in love with me and wants to be with me, but needs time to work things out in his head. He doesn’t want to drag me along to the place where he is and he says this is what’s best for us both right now. Because he knows I deserve so much more than he can give right now.

But I miss him a lot and may friends and family members are angry with him for breaking up with me and asking why we can’t still be together while he gets help?

I have been su*cidal before and I understand that he is not emotionally available to someone else rn when he is not to himself. I want him to get better. He is a good good man that I want to explore the world with later on in life. I still care about him but my best friend told me today, “you deserve someone who is head over heels in love with you” and I do, but that’s him- just not right now. Do I wait for him?
