Dear sia0:

You wrote that your boyfriend “really needs (your) emotional support right now.” And you wrote: “I care about him a lot.” You also wrote that you are “afraid of being alone if he’s no longer there.”

It seems simple to me, the solution to your problem (although I understand the difficulty of your emotions and conflict). This is the simple solution that I see:

Keep offering him the emotional support that he needs. Keep spending time in his company. This way he gets the support that he needs and you will not be alone. You care about him so giving him support and spending time in his company is desirable for you, isn’t it?

What you need to stop doing is the girlfriend/boyfriend stuff, that is the physical gf/bf contact. In other words your relationship transforms to close friendship. If he doesn’t like it, it will be HIS choice to give up the support he supposedly needs.

What do you think?
