Jen,
If you are still around...
After trying to tell the guy I have been seeing for the past few months that I want to date others, he has changed. He has more anxiety and acts like we are an exclusive item. He is upping his for time together when he hasn't seem me for a couple days. Two nights ago, he was at my place late at night. It was so late I told him he could fall asleep. He said , "I don't have my shaving kit on me, but can I sleep over tomorrow night?" I said "Mmm" He said "Mmm?", so I next said "Yes." Although I didn't want to. Yes, he slept over last night.
Kissed me in the morning, told me he loved me and thanked me for breakfast. It is something I do not yet want to make a habit of. In fact, he asked me many times to sleep over his house and I never do. I felt forced in a way , I must admit. He calls me every day after work too. I , like tonight haven't called him back yet.
I do not put it in his face that I am dating other people, but he acts like we are exclusive and invites himself to stay over and calls me every day. It is though he forgot I told him that I am dating others. When he asks me what I have done any particular night, I tell him I was with a friend. I don't share dates with him.
h e l p , p l e a s e , talk about starting to feel consumed. I just got divorced and need to breathe. It is not like I didn't tell him this three times.
I did not call him back yet either.
