Even if you’re desperate, making your ex-girlfriend come back by begging is neither manly nor attractive. So what else can you do? Is it a case of being damned if you do and damned if you don’t? Not really.
Unless you did something wrong and didn’t apologize for it, apologize first. IF you had an affair, be careful not to apologize too quickly. Give your ex girlfriend some time to calm down and then try to initiate contact again. If they still don’t want you back, it’s time to start No Contact.
The only way to get your girlfriend back at this point is to give them space and have patience. If she wants to be friends, be careful if you still have deep feelings. Do you really want to be her friend or her boyfriend?
Does giving a gift count as begging?
In a way, yes, she knows you want her back and using a gift as a way of ‘buying’ her back. It might work for some, but it probably won’t last.
Should you write her a letter?
I don’t feel this is really necessary unless you have unresolved feelings you need to get out. Although I still feel in that regard, you should write your feelings down but NOT send it. Often a letter will not do much good, sometimes even making things worse.
