Search Results: does he see a future with me

my ex boyfriend of 13 months was serious with me and talking about plans for future with me and I was helping him with car Payments every month and he was always there for me to doctors appointments and helped me lose weight and was always there for me and attentive to my needs and very affectionate. We were also living together day in day out and did everything together. He would even cry if I ever wanted to go home and didn’t wanna let me go.
His mom even was teaching me about the Jewish holidays too and invited me over for the holidays as well and bought me a star bracelet.
Back in June we had some arguments and he was unhappy so behind my back he went out on a date with a girl who’s the total opposite of me- gothic punk type and I’m the sweet girly sensitive type. June 28 was when we broke up and then he made the girl opposite of me his girlfriend...
He has always been very private so I’m surprised he wrote a relationship status with this girl on Facebook. Also she’s asking him if he wants to marry her and he was saying he picked out her wedding dress... it’s only been 5 weeks! And he likes to move slow...

he's also telling me he misses me tons and still loves me and gets offended when I disappear/ don’t call him and asks me when I’m gonna come to see him...

is he in a rebound? Or does it sound like he wants to marry this woman to have done a relationship status on fb? (Something he doesn’t usually do)

Me and my ex were together for just over a year and practically living together. We did a lot together - he helped me lose weight, get my drivers licence, and came with me to doctors appointments. We did a lot of firsts together and had/ have a great connection.
He went to jail for 3 months and I waited for him and he was appreciative and happy and was calling me everyday telling me he loves me and was talking about making future plans - we were getting serious and his mom even invited me over for Jewish Passover holiday. Now during the month of June we had quite a few fights over stupid stuff like what I should wear when we go out, my diet and I was also getting irritated when he was on his phone a lot and he was getting overly sensitive anytime I wanted to go back to my house for 3 days and then come back to him. He was scared of me leaving him and he also felt unappreciated , but I always showed him I cared for him - like going to the hospital everyday when he had surgery. Now he starts dating someone who is totally the opposite of me exactly 2 days after we broke up and after 3 weeks they are saying “I love you” to each other. But he says he still wants to work stufff out & possibly get back together. He still kisses me and has me sleeping over at his place during the week and only sees this girl on weekends, but he tells me he doesn’t have history with her like he does with me... and says he needs time and doesn’t prefer her over me right now and that it depends on me and doesn’t know what he wants to do. She’s a dark gothic girl and he’s a classy type of a guy who wears suits and likes to be well dressed and she’s way taller than him and is the total opposite of me - I’m sweet and sensitive, she’s the psycho angry aggressive type and dresses like a punk rocker - totally different from me!
Also it moved very quick - after 3 or 4 weeks saying that they are in love?
Is he in a rebound relationship? And is there a chance for me and him to be back together?
