My ex was cheating on me with his sister-in-law so I had a word with his brother and we decided to pay them both back at the same time. I flirted with his brother in front of him. He didn’t catch on, so I let him know his brother and I went out for a drink - he still didn’t get it, I let him read texts from his brother on my phone - everything. But he was still too thick to get the message. So in the end, I told him I was pregnant and had a scan booked. It wasn’t true, but when he got all excited and volunteered to come to the scan with me and began talking about getting married, I told him that, actually, it was his brother who needed to come to the scan with me. He finally got it.
