How do men get over relationships/women so fast?!? 37,f. 
My bf broke up with me 2 weeks ago,   We’d been together for about 4 years.  We had some issues here and there,  but i really thought things were going very well.    In January we temp received custody of his 5 yo boy,  we had 50/50 before.   
I knew he was quite stressed about work, lawyers fees, promotion etc, but I really felt like I was understanding and supporting.  We had many a conversation about it.   
Come to 2 weeks ago,  he’s acting super strange on his phone a ton,  so I peeked and he had snap chat.  Which may not seem like much, but he loathes social media.  
He broke it off when I asked,  saying he wasn’t attracted to me anymore, and had not been for months and was using me to raise his son 
I’m still struggling with this,  but we work together and on the off chance I see him. He looks fantastic!   
How do I get over this, like a guy?
