Me male 27 her female 33?

My girlfriend is in California dealing with medical issues with her son she is donating stem cells and her kidney to him before she left everything was great and even in the beginning of her being gone but stress had been getting to her and I’ve been nothing but supportive. Well 2 days ago she said she’d like to pause the relationship to focus on her son which should be the priority. And she’s been getting beaten down by life in general. Also she won’t be back for 4-5 months depending on how everything goes

she said she’s being smothered by everything and she feels guilty and selfish she can’t be present in the relationship and it’s not fair to me

Long story short should I trust her word that we will make a come back or should I just end it. Do breaks work? Again her son is basically dying so I very much doubt she’s cheating or anything. But example she freaked out on me a day ago cause I asked for clarification on the break due to it being a first for me and hours later she says she hopes I had a great day like no no I didn’t have a great day cause we are on a break.

Please help is it over do I take a chance that when everything settles or when she’s back it’ll go back to being us or should I just end it
