Do not start your marriage with the expectation that the two of you are joined at the hip. Sit down and have a conversation about how you both feel about separate friends, separate interests, separate trips (hint: you should have all of them).
You married a grown adult woman who should be able to travel on her own to see people who are her friends, not yours. You paid this photographer friend and presumably thanked her for the fine job she did. Your obligations to her are met, on that front.
