[Pretty chef]

Hello Readers. I am having some issues here and don't know how to deal with them.
I have been with my spouse for 14 yrs & have 2 beautiful kids, but never married. But for the past few years I feel as if he is slowly moving forward emotionally. We argue so much and the things he say really hurt my feelings to the point were I feel sick to my stomach. I ask him why don't I know any of your true close friends, why you don't take me around with you sometimes, why don't you do things with me any more. And his explanation is if I don't feel like doing something then I won't do it unless money is involved. He has gotten to the point where his status has changed him in so many levels I ask where do I stand.
For iPhone users there is a social picture sharing app called instagram. Where you post pictures, have followers, follow people, like and comment on pictures. Now I recently added this app not knowing he had it, found him (through my contacts) n added him, majority of his followers and his followings are females. When I looked at their pictures I saw several comments saying sexy, gorgeous, pretty, fat , etc and these were pics of girls showing off their cleavage or face or side profile. Now I confronted him about those comments we argued broke up, he blocked me, and continued arguing so much. He would call me insecure, say "what u jealous", why your hating". Then I would try to explain my feelings towards it n he would say grow up, i dont care about your fake tears, leave me the alone, i can do what i want, im a grown man, mind u he is 32. Then after a month we made up & he unblocked me. So if I comment on his pictures it was okay and he would reply, but if I commented and called him baby there was a problem he would call me right away cursing saying, stop commenting on my pics, you just wanna be seen, there you go with your insecurities, and he would delete it and start arguments.
Today on our anniversary I gave him a challenge. I posted a picture saying happy 14th anniversary stated I loved him, added emoticons, and tagged him in it. He liked the picture but didn't comment on it. Afterwards I text messaged it to him and he replied I love you (in the text reply). So I said if you love me so much and not afraid of it, care about my feelings, and not ashamed of me post this on your page. He called me right away yelling I don't want ppl in my business, mind you he has pics of him n his friends hanging out, a rental maybach, him n celebs, so on. I said but y wouldn't you want to share this special moment in your world. After a few minutes argument He said you, I cursed him back and hung up, i sent him a text expressing my feelings to this situation and he replied "You a little toughen up" & "Or go find somebody else to be with", we argued all day about it, until he finally got mad and blocked me again because I posted a comment on one of his pics saying happy 14th anniversary baby... I love you, which he deleted.
Several times I asked him why is acting like this, what is he hiding from me, or hiding me from.

I don't know what more to do. I tell him leave and he won't he says he needs his family and loves me. I just feel so reckless, at emotional distraught, unloved, and worst than a shadow ( because you can see a person shadow), weak and down. But I put a front for those outside of my home. Been crying all day cause I feel lost. Please someone give me real thoughts. Open to all, & be honest, I can take criticism from others but from him I break down and show my weakness.
