I encourage you to be friends.
But step #1 is getting yourself together emotionally.
Incidentally, I don't believe in "too emotional", but I have seen many cases of 'emotionally repressed', 'attached to emotions', and 'resisting emotions'. The only way around these (that I know of) is learning to relax around your emotions. Accept them. Appreciate them.
Love your emotions!
And perhaps most importantly on a variety of levels, learn to
distinguish between love and attachment.
I think the best strategy for you is noticing the feelings coming up, and letting go of judgment, memories, fantasies, etc. that come up with them. Just keep breathing and returning your attention to the feelings (the sensations in your body) around the relationship.
EFT is a valuable tool, as well.
These are the best 'really getting better' methods... of course there are plenty of 'quick tricks' which work as well, at least on some level... I'll discuss those too, if you like.
keep smiling,
Ben
