<human>: Hi,

Just had a phone call with my girlfriend. She was in bad mode for last few days, turned out she cheated on me last summer. It was a one night stand someone from her summer house and wanted to tell me but it did not mean anything to her so she decided to keep for herself. It seems she failed to cope with this preassure anymore and called me. 

"I dont deserve you" and "Please breake up with me if you broke up with me I understand and cannot argue with you since you are quite good for me" were most used sentences by her during our little chat. I considered it for a brief movement yet said "No!". I want to continue our relationship, she is about to finish her bachelor degree and I am looking for possible Phd programs for myself. Our plan was to apply same universities or at least universities in same cities to live together.

Problem is that I know she cares about me. Maybe because of guilt she tracked down comic books for me, spent stupidly more time with me more than we usually did. I see in her eyes the spark when she looks at me which makes me want to forget everything.

Dont know what to do, I am freezing and I have gastritis so probably will lose some weight as well after months of struggling to gain some.

Can you condense the text into three sentences or less?
<bot>: My SO cheated on me last summer as one night stand, never spoke with him again and confessed me now. Dont know what to do, just want to continue this relationship since I was preparing my proposal.
