I really need help/advice

Bethany

for the last week my partner has been hiding his phone. Being sure not to leave it anywhere with me alone, which subsequently made alarm bells ring. Well this morning I got up and had to use the bathroom and right before I went in he grabbed me in a loving hug. that's when I saw his phone on the bathroom bench. I didn't want to give him a chance to remember it was there either so I quickly dashed in. I couldn't be very long at all so I certainly didn't get a chance to look properly at everything but it was what I feared. Last weekend we had a poker night where his ex girlfriend came around too. I wasn't worried about her. they haven't been togethor since high school (and they're in their thirties now,) and he told me how their relationship was terrible anyway.They fought and cheated on each other. Anyway, I had seen him text her under the table during our card game and I got just a little alarmed when I asked and he said it was his mum. and like I said I didn't see much but she has sent him a naked photo of herself and he's asked about her pussy after having two kids. I know she's having marriage trouble and cheating on her husband but how dare she come near my boyfriend! and ive always told him and shown him when I've flirted with someone else. sometimes I've even asked him what to I should say back but I've always shut it down the moment I knew it was getting out of control. I trust him but him not showing me this and letting it escalate talking about what she can get up her vaginal is breaking it. And how do I talk to him about this? How do you say I've been sneaking on your phone? I don't have a support system here, I left my family behind in w.a. to follow him across the country and he's the only safety net I have here.
