<human>: Can you provide a brief overview of the text?

The long story short and old lady names:

In the past couple months I've had a dramatic drop off in friends due to several military enlistments and general drifting and it has left me lonely. I'm down to one friend whom I see at most twice a month. My girlfriend (Betty) is in a similar vein and we have been helping each other through it, though we both agree friends are a necessity outside of our relationship. I want to reach out to an ex (Marge) whom I believe would be a great friend. Here is where it gets tricky.

I dated Betty for 2 months a little more than a year ago and fell for her hard, the timing wasn't good however and she broke it off. A few months later I met Marge. Marge and I were together for 3 months until about 6 months ago when I decided that I don't feel strongly enough for her to be in a relationship, and simultaneously realized that I had never gotten over Betty. It was then that I acted very poorly by essentially dumping Marge for Betty (no cheating involved). The way I handled it was regrettable to say the least but, despite this, things ended relatively well with Marge, and now Betty and I are together happily. A little FB stalking shows that Marge is in a relationship as well.

When Marge and I broke up we had a "maybe down the road we can be friends" conversation, considerably more realistic than the typical one people might have but not actually mean. I've exhausted my other options first because I knew this could be contentious but the fact is I want a friendship with Marge. I've talked with Betty about this and we've been clear with each other. I have no romantic feelings for Marge and want only friendship. To Betty, the thought of Marge and I spending time together, even innocently, makes her feel deeply jealous. I know it will be awkward and uncomfortable at first, but I wouldn't push the issue if I didn't believe it could work and was something I truly wanted. I love Betty, and our relationship comes first, but I need to take care of myself as well. I haven't contacted Marge and won't until Betty and I agree about this.
