Hi all. I have been seeing someone for the last 8 months. Its quite a long story but I'll do my best to add the necessary details. When we first met he told me after the second night together that he had been seeing someone very casually for a few months and that it wasn't at all serious. He assured me he wasn't going to see her anymore and so we continued seeing each other. We have seen each other 4 or 5 times a week since then, I stay at his house roughly half the week and am deeply in love with him.
For the first 5 months or so, he would 'disappear' roughly once a month. It always turned out he had gone to see the woman he had met before me. Every time he said he loved me he was sorry and he wouldn't see her again..but it kept happening. We werent 'official' at this point but we had said we were going to be exclusive. (We are officially together now). He finally told her about me in January and they haven't seen each other since. I stupidly thought we could finally move on and everything was good for a while.
About 6 weeks ago he met someone on a night out and took her home (thursday) slept with her and then saw me the day after (Friday).The day after he went out with his friends again (saturday), met a woman who was 6 months pregnant in a club, took her home and slept with her. He told me about both of these women on the Sunday - promised again that he would not do it again, he wanted me, he loved me etc.
Fast forward to two weekends ago, he goes out with his friends, gets home at 2am and rings me to say he's home, he's in his bedroom and his (male) friends are downstairs on their own. This turned out to be a total lie, they had all met women that night at the club and took them back to his house. He had rang me to reassure me whilst having another woman downstairs. He slept with her. I sat at home all night anxious and worried and feeling like dirt as I had seen on his friends story that they had women there so I knew he had lied again. I finally got the truth out of him a few days later. He promised me he would never go near another woman again whilst he was seeing me. He said he had felt cold and uncaring all the other times but this time he had hated it and felt guilty and knew he wanted to change.
I stayed. Again. His dad is currently on holiday abroad with his new girlfriend and her family. He told me his dad had asked him to fly out for a week but that he wasn't going to. He then went to the pub that night, had a few drinks, changed his mind and decided he was flying out there the next day. He has been there for one day and I am an anxious wreck. He is reassuring that he is never going to do it again, I can trust him now - 'you know it's different this time', but honestly I'm a complete mess.
How can I possibly move forward and keep my mental health in tact here? I'm so in love with him but this has affected me alot. Thanks
