How do I save my marriage to husband in MLC?

[RLay1100]

Today I'm feeling so sad and lonely. I miss him. I wish H would just snap out of this already. I wish H could realize he DOES love me and our family (not some OW) and come running to me to reconcile. ::sigh::
I'm continuing to have NC with him, except short, to-the-point replies to texts from him (usually about financial issues or kids). Why is he fine with not talking to me, when it is killing me to not hear his voice regularly? He is a little nicer to me, but still very distant when we are face-to-face (picking up/dropping off kids). Yesterday, he got agitated that I couldn't pick the boys up by 4 pm and texted, "Well i got things to do 2". I just knew he meant a date and my stomach sank. :-(
He is continuing to sweet-talk the 19 YO and tell her he loves her, but I also know he is actively pursuing other women, as well. He complains a lot on his social net pages that he is "lonely". Instead of pursuing OW, why not pursue me? -Am I not good enough? -Why?

I am feeling so hopeless right now. I am wondering if I am just being pathetic in standing for my MLC H, when he doesn't act like he misses me or wants anything more to do with me. Is there any hope...?
