How to deal with abandonment problems

Anyone else here have coping mechanisms to stop you abandonment issues from destroying relationships? I had things happen to me as a child that caused this, and it really flares up now and then as an adult. If I really like someone and causes me to get too needy and unnecessary give gifts, and always want to be around someone and inevitably pushes them away. It’s horrible and screws my dating life up so bad. I’m going to a therapist for it but I’m just curious if anyone else who deals with this has coping mechanisms that could help. Thank you so much.
