this is ridiculous
 

i usually see my neighbor every day for coffee and to talk, except for when her bf is over, usually on the weekends. i like her bf and i am very happy for her because she was alone for a really long time, and i respect that they want time alone so i don't go see her when he is around.

but i am bored, lonely, and anxious when i don't see her. it's not the i am jealous of him, i just can't figure out what to do with myself.

It's not ridiculous, it can be hard when you are used to spending time together, however some time apart can be good too as it can help us expand our life into other areas. What about starting a new hobby/activity? Such as cooking or art/writing or even going for a walk or maybe even joining some kind of group to help expand your friendships. Also have a look here, although it is a list of distractions you might find it helpful to give you a few ideas of things to do. Take care

i know what you are saying, and i have hobbies and other friends. not like she is my only contact. i looked at the distractions page, and it's just not for me, thanks. i'm not isolated, and i have plenty to do, i just get anxious when her bf is over. i could go over there, but i WON'T because they only see each other on the weekends and i won't take over their time together. that would be selfish and rude.

What are you anxious about?
Could you not go and see another friend instead? Or phone someone perhaps.
