Women with a lot of guy friends, I really need some advice. Should I be concerned?

Women with a lot of guy friends, I really need some advice.

I have been exclusive with one woman for over a year now. We are not official but we do have an agreement/arrangement. We were out on a date this past weekend and having a great time. We get to dinner and order. She takes out her phone and takes a couple of pictures and sends them to someone. She was doing this everywhere we went. I dont normally ask about it and she usually says something about sending her adult daughter pictures of the places she likes.

However, this time I see the person she is texting is not one of her daughters. She is taking pictures of the bars we are going to but sending them to another man. I am not in the pucture. Right after catching her doing this, I ask who she is sending my picture to? I think im in it and I know she isn't sending it to her daughters. She doesn't hide her phone and leaves it unprotected around me. But she takes another picture and shows me its going to her daughter.

After that, we found a place to make out and fool around but while doing this she asked me if we werent sleeping together would we still be best friends? Had great sex on the way home and In the morning.

She is very charming and very beautiful. Almost everyone loves her. She has a lot of friends but not a lot of close female friends. Her close friends are all men. There have been 2 other men she was talking to but they havnt been around for a few months now. She says they are both friends. My guess is they were both guys that fell in love and she told them no. So they went away.

I do not think she has violated the agreement but every time there is a new guy sniffing around she isnt as good to me but then buys me small gifts that i dont ask for and is hyper sexual when she does see me.

Btw, Ive gotten three gifts from her this week alone. Before her only three women have ever given me gifts, my mother, sister and a friend that didnt really want to be just friends.

She fell first and told me she had feelings but she hasn't told me that she loves me in a while. Feelings are very difficult for her to express but she shares them with me more than anyone in her life. But sometimes she has trouble saying it back but she tell me it at a rand9m moment in the future.

Do I ask her about this new guy or just let it ride? Red or green flags?
