He sounds bloody awful OP, proper psycho scary. Please text him one more time
‘This relationship is not working for me so I’m calling it a day. Please do not contact me again. Best of luck for the future.’
Then block, block block block, and if he tries to get in contact ignore ignore ignore. If he becomes a pest then call the police, but they will only act if you don’t respond to him. If you reply they’ll say you’re encouraging him, so please do be aware of that, because by the sounds of him you might just need them.
Remember, every time you cave in and respond, all he’ll take from it is just how many messages, phone calls, letters, visits to your house etc it takes to get your attention. Each time you respond the whole process will start again, and the start point where he thinks you’re ignoring will be after the 30 or 40 messages it took to get a response the last time.Basically each time you respond will buy you a few more weeks of grief.
Please take this seriously because he sounds like a proper crazy. Rip off the plaster and get him out of your hair as quickly and efficiently as you can. I hope I’m wrong and he’ll just go quietly without a fuss but I’m afraid it doesn’t sound like he will.
Oh, and please ignore the inevitable suicide threats. He will not kill himself over you, he’s not even that bothered about keeping you because he’s refusing to do the things that would make you want to stay with him, so again, ignore ignore ignore.
