There needs to be time to assess and discuss each others feelings. Both hers and yours. She may be experiencing confusion feeling she was not giving you enough. It may have been "mostly harmless" excitement on your part. Regardless of the who, why, how, it is best discussed between the two of you. It is not easy, but it is the only way to get past the fear, hurt, and questions. Gifts and sorry's are nice to a point, but often they just mask the issue and people feel "it goes away" and hit a honeymoon phase. At some point without actual resolution a trigger is likely to occur and open old wounds.

Some space may also be necessary as mentioned above, but not absolute silence. Let her lead the way, ask her what she needs from you.

It may also be worthwhile at some point to review each others feelings about how you met. If there is concern that because of the circumstances that a similar event could occur, that should be addressed to really establish trust.

Best wishes.
