So I've been with my other half for nearly 2 years, recently he's been spending a lot of time on his phone and taking it with him where ever he goes, we've just come back from a weekend away and he completely ignored me all weekend (we went with a few of his friends) Tuesday morning I woke up and saw he was on snapchat, I made a joke out of and he pointblank lied to my face and said that he doesn't even have snap chat,even though I saw him on it, then we went for lunch yesterday and the whole time he kept checking his phone and turning it over so I couldn't see the screen, he point blank refused to sit next to me yesterday on the way home so I had to sit by myself on a 3 hour coach ride him.. Am I being ridiculous to think he's cheating or even talking to another woman? I just don't know what to do
