Don't know what to advise DD (23) to do

[HellloItsMe]

DD (23, left home and working but pops home every few weekends, very close to her) has been seeing (if that is the right term these days!) a similar aged man for about 3 months. She was over the moon as her job has been stressful the past few years and she didn't really have a boyfriend since uni. He seemed a good fit and she was very happy. Only small issue was his job moved to a new city but not too far and at first they saw each other at weekends.
She is now gutted. He is apparently having issues in the new job and unsure what will happen (position he moved to is not what he thought and not a promotion, potential redundancy etc). She said he told her and said how upset/stressed he was but since has barely bothered to contact her. It has been about a week now and about 2-3 weeks since they last saw each other.
She tried not chasing, she tried gentle friendly texts and since has decided to just wait for him to come to her.
She said in any other situation she'd take it as the sign he isn't interested and move on but because of this job drama feels she should be more understanding. She doesn't want to throw it all away but equally doesn't like his approach of cutting her out when times are hard.

She asked me what I think, but I don't know what to advise her. I said for now just keep busy and let him realise what he is doing to her but I understand it is hanging over her and she doesn't want him to think it is alright to cut her out should they end up continuing the relationship.
Help!

It sounds like this has run its course. She needs to concentrate on her own self and life now because that is what he is really doing now.

I would question her idea about being more understanding due to his job situation; he has not bothered to contact her at all. As for the idea of throwing a relationship away we throw litter away, not relationships.

Thanks, sorry to add (avoiding drip feeding, this is the one thing I forgot) she said he tried to phone earlier this weekend but she was with a friend and tried to call back later but no answer.
Don't think it makes much difference tbh but she is holding onto every little hope. I do think she needs to see is realistically but I know also what it is like when you are in these situations, you don't see things realistically.

I think attila is right, she needs to concentrate on herself and her own life. If he wants to get back into contact he will. As for what you can do, I don't suppose you can do much except to be there for her in case it doesn't work out.
