My ex and I split 8 months ago, and he immediately moved out of the family home. We have had our ups and downs since then, but it has generally been pretty amicable,and very amicable around ds.
He has our 2 year old son for a day and a night every weekend, and occasionally sees him for a couple of hours midweek, maybe collecting from nursery and dropping home to me.
Ds has always been fine, and happy to go to either of us, but has suddenly started pining for his dad in the most heart wrenching way. Talks constantly throughout the day about seeing daddy, going in daddy's car, daddy come to door? Etc etc. I honestly don't know where it's suddenly come from. Ex dp picked ds up from nursery today, dropped him here, and stayed for an hour or so playing. When he left ds had the most horrendous tantrum I've ever seen. He was beside himself, and continued to weep on and off about 'daddy' till bedtime 
.
I am so upset. Is this likely to be just a phase? I suddenly feel like I am inflicting terrible emotional damage on him by ending the relationship with dp. I am also planning to move closer to work in the next couple of months, which will mean a change of home AND nursery for ds . Will he cope? Please tell me at 2 years he will adapt and be fine? Reuniting with ex dp is bit an option, he was an abusive and unpleasant partner.
