I am going through heartbreak too, I was going to start a new thread then saw yours and thought I'd message on here.
My now ex OH finished with me on Monday. Big shock as it was so, so sudden. Completely out the blue. The day before he was texting me saying how much he loved me etc, so I was completely floored by the phone call I received on Monday evening saying he didn't wish to be with me anymore.
I went into autopilot I think, I can't remember what happened on Monday night, I just remember the phone call ending, lots of tears from me and then going to bed.
It's been 5 days now and I'm eating a little, trying to look after myself. I've been trying to keep busy, as if I don't then all I do is think about him and the relationship. I sent him an email on Tuesday morning basically pouring my heart out asking for a reason as to why but he never replied and I've had silence from him. I have a horrible gut feeling he's met someone else and is too scared to admit it. It's bloody gutwrenching to be honest.
OP, I found surrounding myself with friends and family really helpful. I live quite far from some of them, but it was nice to have them on the end of the phone. Evenings and nights are the worst so I have been making myself super busy then, good movies, a good book, a nice bath, anything that will take my mind off him. I find reading makes me super sleepy so I always make sure I read a lot before bed.
Lots of good suggestions about looking after yourself on this thread. It's horrible when you want to eat but feel like you physically can't. I think it's very very important to be kind to yourself especially during the first few weeks or months, it's a shock to the system.
I've been reading a lot about breakups and heartache and I see it's very good to have some sort of goal to focus on. I am guessing that comes later on once the initial shock has worn off. I am thinking of various exercise classes to join and perhaps an evening class of some sort, just something I can work towards and focus on.
Like you, I am thinking to myself 'he made me feel so good about myself, why has he decided to do what he did?' It's horrible when you don't even know if you'll get an answer - I am sat constantly looking at my phone sometimes hoping he'll call or text, but I'm starting to think it's a waste of time and I should be focusing on myself and getting myself back to normality.
Lots of
and
for you. It's comforting to know there's others out there who we can chat to about this.
