Search Results: boyfriend might be cheating

My boyfriend and I have been together for a year. We started off as hella romantic he would send me random text and message me like a lot waiting for me to reply. He was so mushy and romantic. Then suddenly it all went away.. He just agrees to things now... And like once we were skyping and his bro was like "wait that isn't your girlfriend" then suddenly it went to mute. I blocked the screen and cried a little. Because he might be cheating I live in Oʻahu Hawaiʻi but he lives in California... So the distance plus he lied about having and instagram and he just won't put my name in like his bio or anything but he likes that I have his. I wish he'd put it in because that way I would be sure it was for me... Shoots he doesn't even let me follow him on instagram... I've talked to him but he gets all emotional and says he's not cheating then I feel back and just shut up about it... He says we're going to get married after we gradute and we're ready and i'm totally down for that but i'm just worried i'm not his only girl... I just need help with processig all of this.. I like want to know why he isn't mushy anymore and like why he won't put my name in anything... I know it's stupid and all but I just don't know.. I know i'm in love with him but like I don't know I just really want to know why... Help anyone please

My boyfriend accepts that he talks to random girls online and searches for true friendships. But it is only girls somehow. Plus i thought its extremely fair of me to question this and to let him know it might be a little weird to me. But he got upset. I really dont get whats going on on his mind. and bringign this topic up seems to only make it worse. he doesn't even try to explain to the fact. he calls girls online hot and says its normal. its just fun. I know he would never cheat on me. He is into me for sure. But what is with this online stufff?

I have been an unlimitedly selfless, thoughtful, generous, forgiving, patient girlfriend who has accepted all flaws despite everything. So many huge gestures have been done on my part. I have made massive sacrifices for this man. So if I find out he's even cheating, I just may honestly overstep physical boundaries just as he carelessly overstepped emotional boundaries.
I consider spitting in his face so he can physically feel how disgusting he is. Then I would punch him hard so he can have no choice but to feel the same heartwrenching pain and violation he has caused me.
Is this all crazy and backwards? What are your thoughts on a situation like this?
