The 34-year-old won his 75th cap for his country in Friday's disappointing 2-1 defeat in Macedonia and is set to win just three more after stating he would stand down when the current World Cup qualifying campaign ends in Belgium next month.
Despite a frustrating Group A effort which has yielded just two wins, both against Scotland, from seven games, Bellamy believes the future is bright for Wales with talents of the calibre of Gareth Bale, Aaron Ramsey and Jonathan Williams to call on.
But the Cardiff and former Celtic forward, while not completely ruling out a change of heart, is not tempted to prolong his Dragons career for one more campaign as he wants to spend more time with his children.
He also revealed he may step down from all football when his current contract ends following the culmination of his club's maiden Premier League campaign.
When asked if he could yet continue playing for Wales, Bellamy said: "I don't think that's going to be possible. I know I said I would not retire from international football and I really want this group to succeed.
"But it's a two-year period to qualify and if I start (the campaign) then step aside, it is robbing someone else of two or four matches, of vital experience, and they would miss out as well.
"That's the way I'm looking at it. I honestly think Wales have a great chance of doing something but I've thought about it really hard.
"It's difficult. I'm a single parent now and I'm having such a battle to see my kids on a daily basis. It's so hard.
"Then, being away for 10 days, I'm not the only dad who has to go through it, but if you have experienced it, then you would understand."
He added: "My mood does change...I know I could change what I'm thinking.
"But the way I'm feeling now, it could be my last season in football.
"I have so much to look forward to after football. Life isn't just about football. The adventure starts when you finish and I'm looking forward to that.
"I've been playing at a professional level for 17, 18 years now and there's more to life. I love the game, don't get me wrong, I've cherished every moment of it."
But Bellamy would welcome the chance to go into management once he hangs up his boots for good.
He said: "I've got my A licence already, then I'm doing my pro-licence.
"After that, I'm going to travel around the world - Spain, Argentina - and learn my craft. I don't just want to go in and mess about. When I go in, I'm going to be prepared and I'm going to stay in."
