I can certainly relate to this topic! When I had been seeing my T for a while, she went out of the country and I kept telling her I didn't want her to go, or that I wanted to go with her! It was awful when she was away that time.
I've been seeing her for about 5 years and I know she's not going to abandon me on purpose, but she could still leave, or she could die. When she got divorced, I was sure she was going to meet someone and move away, or she was going to move back to her original state. She reassured me that her job was here and she wasn't going anywhere. I trust her, but you never know. Anything may happen.
She's away now on vacation until Sunday. I can't believe the time is almost up. I still worry that the plane may crash, but I worry about that with anyone who drives or flies, including myself. She used to tell me "I'll be back" when she went away, and I know she means it, but I told her "no one ever knows." It's very hard not to worry about a T leaving.
I was afraid I'd have to leave her when my insurance wouldn't cover her fee anymore. Then she gave me a reduced rate. She truly doesn't want to abandon me by choice, but it can happen. So I understand and empathize, Teddy.
