Helpfultoothers, I was dating a meth addict that went to rehab about two months into our official relationship for a year and it was unstable. The last breakup just dealt me a huge blow and broke me apart. With the help from so many on this forum, I was able to take a step back from the craziness and look at everything, mostly myself. I truly believe it's time to put the loving focus on yourself, if you haven't been doing that, because you deserve and need that. Nurture yourself so that you can grow into the woman you want to be. Then before you know it, the right person will be finding you.
I completely understand about the heaviness in the chest as that's what I dealt with with my ex a lot. It's very difficult and tough, but just try to breathe through it.
