Five years ago my then-wife kicked me out for being a drunk. Today I got dumped for being sober. At least I won't wake up with a hangover this time.
One day you will find the right person and they will love you for you and your sobriety don’t get down about it all it means is they weren’t ready to be loved by someone with a sober mind they will regret it but you will be to far focused to even look back at what they are missing out on keep moving forward with your sobriety
To thine own self be true my friend!! Good for you for handling it the way you are! 
Relationships are so tough. Glad you're still sober, sorry for the pain. But it sobriety has to come first or we're not even really us, and I, personally, lose even people who are daily in my life.
I recently broke up with a man I love because his drinking is too much for me. 🤷
This life stuff can be so painful.
Stay close to your sober friends, keep working your program... Waking up sober is so worth it all!
Stay positive & true to yourself.
